Application of Hydrolysis

2. Application of Hydrolysis
Tums
CaCO3
Basic Salt neutralizes stomach acid
CaCO3 ⇄ Ca2+ + CO32-
CO32- + HCl  HCO3- + Cl-
HCO3- + HCl  H2CO3 + Cl-

3. Application of Hydrolysis
Salt and Vinegar Potato Chips
NaCH3COO(S) C3H5O3COOH(S) + H3C6H5O7(S)
Sodium acetate Malic acid Citric acid
Basic Salt All of the above are solid and can be added in large quantity without making the chips soggy.
NaCH3COO  Na+ + CH3COO-
CH3COO- + H2O ⇄ CH3COOH OH-
Malic and Citric acid increase the [H+], which lowers the [OH-], shifting the reaction to the right making more vinegar.
