    Simplify these pH solutions - I don't wanna memorise em

    xdx.jpg

    Regarding 'the effect of pH on enzyme activity', we have to remember how to make those pH solutions (click the above attachment).

    Is there a method of simplification I can use for an exam?

    I want 5 test tubes, with pHs 3, 5, 7, 9 and 12.

    Is there a simple method I can use, something such as:

    -add 1 drop of x into beaker 1, check its pH (litmus paper + universal indicator chart), keep adding a drop and checking its pH until its a pH of 3.

    - repeat for all pHs

    I believe you answered your own question there, mate!

    Oh, except, you can't precisely repeat that, because you want different pH's. So say perhaps "repeat for all pH's, except adding one more drop for every time the pH needs to be raised by 1." IDK the content, so sorry if this doesn't make complete sense, but hopefully you can understand what to do.
