PROBLEM 74P

Write balanced complete ionic and net ionic equations for each reaction.

(a) HI(aq) + KOH(aq) → H2O(l) + KI(aq)

(b) Na2SO4(aq) + CaI2(aq) → CaSO4(s) + 2 NaI(aq)

(c) 2 HC2H3O2(aq) + Na2CO3(aq) → H2O(l) + CO2(g) + 2 NaC2H3O2(aq)

(d) NH4Cl(aq) + NaOH(aq) → H2O(l) + NH3(g) + NaCl(aq)

Solution 74P

Here, we have to write the balanced complete ionic and net ionic equations for each reaction.

In balanced chemical equation, the number of each type of atom or ion on both sides of the equation should be equal.

(a) HI(aq) + KOH(aq) → H2O(l) + KI(aq)

Total ionic reaction is

H+ (aq) + I- (aq) + K+ (aq) + OH- (aq)------> H2O(l) + K+ (aq) + I- (aq)

Spectators: I- (aq), K+ (aq)

Net Ionic Equation is : H+ (aq) + OH- (aq)------>  H2O(l)

(b) Na2SO4(aq) + CaI2(aq) → CaSO4(s) + 2 NaI(aq)

Total ionic reaction is

2 Na+ (aq) + SO4 2- (aq) + Ca2+(aq) + 2 I- (aq) -------> CaSO4(s) + 2 Na+ (aq) + 2 I- (aq)

Spectators:...
