Strong acid so it will ionize 100% [HBr(aq)] = [H O (aq)] 3 +

Answer 1:

Correct! 6

Weak acid - will ionize less than 100%. You need to use the
equilibrium law expression. The acid concentration is more than 1000 times greater than the Ka value, therefore any decrease in concentration due to ionization is considered negligible and the equilibrium concentration of the acid is assumed to be the same as the initial concentration.
