Most of the neutralization questions deal with acid and base and we want to make the product neutral or pH=7.

I won't copy the exact word due to copyright.
#62 says ??mL of ??M solution of Ca(OH)2 is added to ??mL of HBr. what is the concentration of the HBr?

in this question, it didn't say whether we want to make the product neutral or acidic or basic so how am i supposed to know that we are trying to neutralize it?

Members don't see this ad.
 
#62 says 20mL of .012M solution of Ca(OH)2 is added to 48mL of HBr. what is the concentration of the HBr?

Umm...perhaps think of it as a dilution, then think of the dilution formula, except you use normarlity instead of molarity because Ca (OH)2 has 2 equivalents. then its pretty easy from there.
