what is white precipitate and why does it happen?

Can you give us a little more context?
I’m guessing you’re talking about why precipitates form in some cases when you mix two liquids together. In that case, it is because the chemicals are reacting with each other, and at least one product of that reaction is a non-soluble solid. In that case, as it forms it falls out of the liquid as a precipitate.
A precipitate is a product of a chemical reaction that is not soluble in the solution. The color is determined by what it is exactly but it isn’t soluble for a variety of reasons such as the acidity might be wrong for it to be soluble or the solvent isn’t the right polarity for it to dissolve. Think many things are dissolvable in water, it’s called the universal solvent, it is polar because one side of the water molecule tends to have a negative charge and the other has a positive, because of where the electron concentration is. Some things are not dissolvable in water, but they are in oils or other solvents like benzene which are non-polar meaning it doesn’t have a positive and negative side.
A precipitate is something that didn’t dissolve into the solution.
It could be *literally anything* because no one here knows what you put into the solution. The fact that it’s white is pretty meaningless.
