I am making a mix with the following ratios
water 1200 litres
Phosphoric acid 250 litres
potassium hydroxide 360 kgs
When I add the hydroxde to the acid water it give off a violent reaction and heats up.
Initially adding the hydroxide the reaction is muted. but the more I add the more violent the result.
Is there any way of mixing this mix to lessen the reaction?
