HBrO(aq) + NaCl(aq) ----------> NaBrO(aq) + HCl(aq)
HBrO is weak acid . It is partialy ionizable.
K>1 hace there will be mostly reactants at
equilibrium>>>>answer
Q8.
LiBr(s) -------> Li^+(aq) + Br^-(aq)
KNO3(s) --------> K^+ (aq) + NO3^- (aq)
only i would be more soluble in an acidic solution
>>>>>answer
Q9.
Ni(OH)2(s) ---------> Ni^2+(aq) + 2OH^_(aq)
----------------------x ---------- 2x
Ksp = [Ni^2+][OH^-]^2
6*10^-16 = x*(2x)^2
4x^3 = 6*10^-16
x = 5.3*10^-6
[OH^-] = 2x = 2*5.3*10^-6 = 1.06*10^-5
POH = -log[OH^-]
= -log(1.06*10^-5)
= 4.975
PH = 14-POH
= 14-4.975
= 9.0
9.0 >>>answer

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
