Cynthia combines 1.7 grams of Silver hydroxide with 234 ml of a 1.2 M solution of HBr. Assume all the silver hydroxide dissolves once it is in solution(which is technically not the case, but for this example, just go with the flow of it).
What will be the final pH of the resulting solution once equilibrium is reached ?
OK. I'm going with the flow.
...Ag(OH)2 + 2HBr ==> AgBr + 2H2O
mols Ag(OH)3 = grams/molar mass = ?
initial mols HBr = M x L = ?
mols HBr used = 2*mols Ag(OH)2
mols HBr remaining = initial mols - mols used = ?
Then M HBr left = mols/L
and pH = -log (HBr) = ?
