Homework Help: Chemistry

Posted by Sarie on Sunday, September 19, 2010 at 11:32am.

Could someone please help me with these two questions. I am having trouble.

1. What is the molarity of a solution if 48.0 mL of a 0.220 M solution is required to neutralize a 25.0-mL sample of the solution?

2. The mixing of which pair of reactants will result in a precipitation reaction?

K 2SO4(aq) + Hg2 (NO3)2(aq)

CsI(aq) + NaOH(aq)

HCl(aq) + Ca(OH)2(aq)

NaNO3(aq) + NH4Cl(aq)
