born2dive9702 Posted November 6, 2018 Share Posted November 6, 2018 If I have an acid say phosphoric acid which has a ph of 4, and a citric acid with a ph of 4 will the ph still be 4, (because both are independant) or will the ph go down to say 3 because the sum of the 2 parts are greater than the whole? please let me know Thanks Brad Link to comment Share on other sites More sharing options...

Sorry I am not a chemist nor have taken any chemistry classes. My gut instinct is that it is a total of the sum so the ph would down from 4 to 4 . But again this is my gut instinct and I am no chemist. I am a language instructor. Link to comment Share on other sites More sharing options...
