    The most important thing to keep in mind with celebrity actors is that they make a living pretending to be someone/something they’re not. And they’re damn good at it too.

    Not to cast doubt on everyone in that profession. Rather, proceed with an abundance of skepticism when considering celebrity endorsements.

    The best way to remain beautiful your whole life is being born in a family of (white) millionaires, remain a millionaire through inheritance and by working on your family’s cushy business without ever having to worry about nothing for not even a second of your life and also having access and being able to aford the most modern and technological advancements in beauty. If that is not enough and you still feel time is getting close you can create your own fake science and get even more money (maybe that helps?)

    Not defending pseudoscientific health regimens, but the acid in “a spritz of lemon” doesn’t neutralize an arbitrary amount of alkalinity

      No, but it does reveal a distinct lack of understanding on her her part as to what these pseudoscientific health products even are that are supposedly doing things for her. Like saying “I always drink decaf coffee and pop a shot of 5 hour energy in the morning.” “I drink skim milk with a splash of double cream.” “I love honey on my keto toast.” Like, even if it’s not enough acidity to completely negate the alkalinity, it’s literally antithetical to the supposed goal.

      I think it was Angela Collier that did a pretty basic test with a common store bought alkaline water, a lemon and some test strips. The water doesn’t start very alkaline at all.

      It’s an amusing video.

        She did the math (with some assumptions), but basically 0.25 mL of lemon juice will turn 500 mL of alkaline water into neutral water:

        This is in the video at 13:16.

        The reason is that pH is a logarithmic scale. Alkaline water has a pH of about 8, which means it has a tenth of the hydrogen ions compared to neutral water at pH 7.
        Lemon juice has a pH value of 2, which is 1,000,000 times more hydrogen ions than there are in pH 8. So, you just need a little bit of lemon juice to increase the hydrogen ions in alkaline water tenfold, which makes it neutral.

          0.25 mL of lemon juice is probably too much already.

          She’s doing the maths for the concentration of citric acid in lemon juice through the formula C(acid) = 10^(-pH). That works fine for a strong acid, because you can be pretty sure all that acid in the solution is dissociated, and thus lowering its pH… but citric acid is weak - and weak acids don’t dissociate properly in already acidic conditions.

          This means there’s probably way more acid in that solution than the pH makes you believe, but that acid will react once you raise the pH, by mixing the lemon juice into the water.

          (I don’t blame her for using the strong acid maths. It’s already enough to convey her point, plus the maths for weak acids is a bloody pain.)

        Even regular neutral water shifts to slightly acidic (5.6) as long as it has contact to air (CO2 dissolving). Would be interesting to know how long those store bought alkaline water becomes base or acidic.

            I gave an example. To show your double standard. And it is working.

            Speaking up for atrocities towards other groups is something. Getting offended on behalf of other groups when no member of that group is feeling under attack is something else.

            Like women?

            I really don’t get it. I go to another thread on reddit and they call me a wokescold for speaking out on a insanely sexist joke. And I get called a misogynist here because I want people to treat women and men equally. Acting like women are more fragile than men is inherently sexist

            Tbh, it’s been a lot since the last time I called someone a “pussy”. Because I think it’s belittleling to women. But I frequently call people a “dick”. Which is derogatory towards men and I shouldn’t use it either. Turns out, slurs are created to offend people, who would’ve guessed

            I can’t count the times a neurotypical got offended on behalf of me. Those people also do a lot of belittleling. So much infantisation in fact, I would rather have them call me the r word. Or the times a christian got offended on behalf of me (back then when I was a muslim). It’s annoying af

    Sorry to disappoint y’all. This is actually not so dumb. Chemically she makes a buffer solution.

    How a Buffer Solution Works: Example with Baking Soda and Citric Acid

    A buffer solution is a system that resists changes in pH when small amounts of acids or bases are added. Buffers are essential in chemistry and biology because many processes require a stable pH.

    How Buffer Solutions Work

    A buffer usually consists of a weak acid and its corresponding conjugate base (or a weak base and its conjugate acid). When an acidic or basic substance is introduced, the buffer reacts to neutralize the added ions, thus stabilizing the pH.

    • When an acid (H⁺) is added, the buffer’s base component reacts with it, “soaking up” the excess H⁺ ions.
    • When a base (OH⁻) is added, the acid part of the buffer reacts with it, neutralizing the excess OH⁻ ions.

    The ability of a buffer to do this depends on the presence of both a weak acid and its conjugate base in appreciable amounts.

    Buffer Example: Baking Soda (Sodium Bicarbonate) and Citric Acid

    Ingredients Involved

    • Baking soda (sodium bicarbonate, NaHCO₃): A weak base that can act as a proton acceptor.
    • Citric acid (C₆H₈O₇): A weak acid, commonly found in citrus fruits.

    When these two substances are dissolved in water, they interact according to the following reaction:

    $$ \text{C}_6\text{H}_8\text{O}_7 + \text{NaHCO}_3 \rightarrow \text{C}_6\text{H}_7\text{O}_7^- + \text{Na}^+ + \text{H}_2\text{O} + \text{CO}_2\uparrow $$

    This reaction creates a mixture containing both citric acid (weak acid) and its conjugate base (citrate ion).

    How This Buffer System Functions

    • If an acid is added to the solution (increasing H⁺), the citrate ion (Citrat-Anion) from the reaction will bind to the excess H⁺, lessening the pH shift.
    • If a base is added (increasing OH⁻), the leftover citric acid will release H⁺, which neutralizes the OH⁻, keeping the pH stable.

    Key Point:
    This buffer is only effective within a certain pH range, which in this case is close to the pKa value of citric acid (around 3-7 depending on which proton is being lost, as citric acid is a triprotic acid).

    Summary Table

    Component Role Action if acid is added Action if base is added
    Citric acid (C₆H₈O₇) Weak acid Conjugate base absorbs H⁺ Releases more H⁺ to neutralize OH⁻
    Sodium bicarbonate (NaHCO₃) Weak base (forms buffer) Provides conjugate base (citrate ion) Provides weak acid (citric acid)

    This mixture resists pH changes thanks to the reversible interplay between the weak acid (citric acid) and its conjugate base (citrate ion), demonstrating the core principle of buffer solutions.

            Because having salt of an acid out of a citric fruit in water, makes it tasty.
            I just use some black salt, though. Much cheaper.

            It’s not dumb in the sense that water that is not alkaline is not the same as water that is alkaline with some added acid.

            In Eastern Europe the soft drink created by mixing sodium bicarbonate into water and then adding a tea spoon of lemon juice or vinegar to it was an oft used refreshment before the 80s.
