Sodium Hydroxide, Sulfuric Acid, and Slush
When mixing Sodium Hydroxide with water (50%-50%) then
using Sulfuric Acid to neutralize, should you get a crystal (grain
of rice size) that is kind of slushy in consistency at the bottom of
Try writing the balanced equation for the reaction: NaOH + H2SO4 ==> Na2SO4 + HOH. Look up Na2SO4 in a table of solubilities. Is it soluble or insoluble. If it is soluble, what would happen if you gently heated the solution to dryness in an evaporating dish? What would you call the solid that is left?
