use as strong alkali
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
when the solution turns blue you add the sodium hydroxide (also if it is not blue you have gone wrong stupid)
When 10g of sodium are put into 100g of water, the reaction produces only 109.6g of sodium hydroxide because of the sodium's solvency. Some of the sodium is displaced in the reaction, and this is why it does not seem to add up.
Add 5 g of sodium hydroxide to 95 g (or 95 mL) of water to get a 5% solution.

A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
Acid

add sodium or potassium hydroxide.
You will get a pink to a pinkish-red solution depending on how concentrated the sodium hydroxide (NaOH) is.

You would need to add Sulphuric acid to make Sodium Sulphate + Water :)
Add acid and neutralize the solution.
Sodium react with water forming a base - sodium hydroxide - and releasing hydrogen. Add an acid for neutralization.
