Question:
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 the beaker?

Replies:
Jerry,

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?

Mr. Young
