The insoluble base is magnesium hydroxide, #"Mg(OH)"_2("s")# and the soluble acid is hydrochloric acid, #"HCl(aq)"#.

Explanation:

Magnesium hydroxide plus hydrochloric acid produce magnesium chloride and water.

#"Mg(OH)"_2("s") + "2HCl(aq)"##rarr##"MgCl"_2("aq") + "2H"_2"O(l)"#

You could evaporate the water to obtain solid #"MgCl"_2"#.

The insoluble base is magnesium hydroxide and the soluble acid is hydrochloric acid.
