The problem is "Identify the salt that is produced from the acid–base neutralization reaction between..." I am having trouble with c. calcium hydroxide and bromous acid

I think it's just finding the two ions from the acid and base, matching the charge, and then putting them together. Ca has a 2+ charge since there are 2 OH- and HBr has Br-. So the neutralization result should be CaBr2, or Calcium Bromite as the textbook says.

Bromous acid is hydrogen and bromite, so bromous acid is HBrO2.

Ca(OH)2 + 2HBrO2 -> Ca(BrO2)2 + 2H2O

Answer is Ca(BrO2)2

Why does the textbook split up the salts into their elements in the answer key, for instance instead of the products being written as a salt + water, the salt is split up like 2Na + S + H2O instead of Na2S + H2O?
