General Chemistry help!

What is the precipitate which forms and then redissolves upon adding H2SO4 to the mixture of K+, [Al(H2O2)2(OH)4] and OH-? Calculate the volume of 6.0 M sulfuric acid H, SO, , solution required to neutralize the excess potassium hydroxide, KOH. solution from the first step of the synthesis. Indicate clearly your calculations and reasoning. Calculate the theoretical yield of the precipitate in a. Assume that you started with 1.00 g of Al(s) and could produce and collect the precipitate quantitatively. Indicate clearly your calculations and reasoning.

Explanation / Answer

Al(H2O)3(OH)3

B. Calculate the volume of 6.0 M sulfuric acid H2SO4 , solution required to neutralize the excess potassium hydroxide, KOH, solution from the first step of the synthesis. Indicate clearly your calculations and reasoning.

    Mol KOH excess = total moles KOH
