What volume (in mL) of a solution 0.160 M in Ca(OH)2 must we use to neutralize 29.0 mL of a solution 0.337 M in H3PO4.  

We have 2.82 L of an aqueous NaBr solution. We add an excess of AgNO3. We form 8.94 g of AgBr(s). What was the initial concentration of Br- (in mol/L) in this aqueous NaBr solution?  

What is the pH of a 0.100 M solution of the acid HA if its ionization constant, KA, is 0.32 .
