Question

Write the balanced chemical equations for the following equations:
a) Sodium carbonate on reaction with hydrochloric acid in equimolar
concentrations gives sodium chloride and sodium hydrogen carbonate.
b) Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium
c) chloride, water and liberates carbon dioxide.
d) Copper sulphate on treatment with potassium iodide precipitates cuprous
iodide(Cuzla), liberates iodine gas and also forms potassium sulphate.​

Answer 1

(A) Na2Co3+2HCl= 2NaCl+ H20 + Co2

(B)NaHCo3+HCl=NaCl+H20+Co2

(C)CuSO4+4KI= CuI2 + 2K2SO4

Answer 2

Answer:

a) Na2CO3 + HCl = NaCl + NaHCO3

b) NaHCO3 + HCl = NaCl + H2O + CO2

c) CuSO4 + 4KI = CuI + I2 + 2K2SO4
