The relationship between sodium hydroxide and copper is well known, says a chemistry professor at Laurentian University. The interaction of the metal with the chemical is being closely watched by ...

Sodium hydroxide solution is added to copper sulfate solution. Solid copper hydroxide is produced in sodium sulfate solution The table shows the coloured precipitates formed by five common metal ions.

The solid copper hydroxide precipitate was collected by filtering, washed with water and dried in an oven. It was found to weigh 1.95g and from this we can calculate the mass of copper sulfate in ...
