1 point
Pbo + HNO3 -------> Pb[NO3]2 + H2O
CuO + H2SO4 ------ > CuSO4 + H2O
NaOH + HNO3 -------> NaNO3 + H2O
NaOH + Zn[NO3]2 ------- > Zn[OH]2 + NaNO3
​

Answer 1

Answer:

Back titration works in the following manner (with an example) : 1: The substance or solution of unknown concentration (4 gm of contaminated chalk, CaCO3 ) is made to react with known volume and concentration of intermediate reactant solution (200 ml, 0.5N HCl). The reaction goes past the equivalence point
