Homework Answers
Solution :
1) For the given reaction, the balanced equation will be written as,
2HI (aq) + K2CO3(aq) = 2KI(aq) + H2O (l) + CO2(aq)
Complete ionic equation will be :
2H+(aq) + 2I-(aq + 2K+(aq) + (CO3)^2-(aq) == 2K+(aq) + 2I-(aq) + H2O(l) + CO2(g)
Net ionic equation will be :
2H+ (aq) + CO3^2- (aq) == H2O(l) + CO2(g)
2) The neutralization reaction between NaOH and H2SO4 can be written as,
2NaOH + H2SO4 == Na2SO4 + 2H2O
Thus, 1 mol of H2SO4 required 2 mol of NaOH.
According to molarity equation,
M1 V1= 2 M2V2
0.0134 M x 23.9 mL = 2 M2 x 31.5 mL
M2 = 0.0051 M
