A home-made smell remover

This task is about mixing everyday substances to bring about a chemical change.
illustration: fish on a plate
All fish smell "fishy" because they contain unpleasant-smelling substances called amines (which are bases). When lemon juice (an acid) is squeezed on to the fish, this smell disappears.

Question 1Change answer

a)  What name is given to the reaction between an acid and a base?  

Question 1Change answer

b)  Why would this reaction make the smell go away?

Question 1Change answer

Lemon juice is expensive and you’ve been asked to come up with a cheaper method to get rid of those fish smells in a kitchen where you work part-time. People you ask for ideas make various suggestions of combinations of substances you could try. Now you need to evaluate them. 
Which is most likely to work and why? Could any of these pairs of substances be used to remove the "fishy" smell? Think about which substance might be acidic to begin with, and whether they stay acidic once mixed. Might any of the pairs turn acidic after they are mixed?
