I think that the amount of hydronium ions goes down and the number of hydroxide ions goes up.
If you add the same quantity of an acid and a base it will become neutral.i.e forms salt and water
It will neutralize the mix.
what answer
They neutralise each other, assuming you neutralise a volume of acid with a base of the same molarity they completely cancel each other out leaving water and a salt. The salt differs depending on the acid and base used.
and add it to water
this emans to water it down, or add water...
The pH remain unchanged.
When you add a base to an acid, they undergo a neutralization reaction to form water and a salt. The general chemical formula for this reaction is: acid + base → salt + water
Nothing
crystals form
it turns brown?
You get a solution.
