basic = pH>7
A. pOH = 7 - log 3.31, pH = 14 - (7 - log 3.31) = 7 + log 3.31 (basic)
B. pH = 9 - log 8.17 = 8.09 (basic)
C. pH = 4 - log 5.91 (acid)
Reactants are NaHCO3 and HC2H3O2 because they are on the left side of the arrow, aka they’re what’s going in to make the products. NaC2H3O2, H2O and CO2 are the products bc they’re on the right side of the arrow, aka they are the results of the reactants combining
