The optimum pH of formic acid - formate buffer is 3.75
<h3>What is pH? </h3>
- pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
- pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
What is Buffer ?
A substance or a solution which resists any changes in pH, when acid or alkali is added to it.
pH = pKa + log[base] / [acid]
Considering equimolar concentration of acid and base
pH = 3.75 + log(x)/(x)
pH = 3.75 + log (1)
pH = 3.75 + 0
pH = 3.75
Hence,
The optimum pH of formic acid - formate buffer is 3.75

Explanation:
No 11) one mole of Zn and two mole of HCL to get one mole of ZnCl and one mole of H2.
no 12) one mole of Mg and two mole of AgNO3 to get one mole of Mg(No3)2 and two mole of Ag.
no 13) one mole of CaCl2 and two mole AgNO3 to get two mole of AgCl and one mole of Ca(NO3)2.
no 14) two mole of Na3PO4 and three mole of BaCL2 to get one mole of Ba3(PO4)2 and six mole of NaCl.
no 15) two mole of NH4Cl and one mole of Ba(OH)2 to get one mole of BaCL2,two mole of NH3 and two mole of H2O.(am not much sure about this).
no 16) one mole of Na2CO3 and two mole of HCL to get two mole of NaCl,one mole of H2O and one mole of CO2.
no 17) one mole of K3PO4 and three mole of AgNO3 to get three mole of KNO3 and one mole of AgPO4.
