please help ><
Polyprotic acids have more than one proton to donate to water, therefore have more than one equilibrium constant for proton donation. For phosphoric acid, there is a three-step equilibrium: H, PO +H,0 5 H2PO4 + H30* H,PO," +H,0 5 HPO - +H30* HPO 2- +,0 5 PO.- +,0* Kai = 7.11 x 10-3 Ka2 = 6.32 x 10-8 Ka; = 4.5 x 10-13 For all conjugate acid base pairs: K, XKK where K is for the reaction...

Consider a solution prepared by dissolving 3.30g of barium hypochlorite salt in 0.660 L of water at 25 degrees C. (Assume solubility of the salt in water). Ka = 3.0x10^-8 1) Write and balance the reaction according to which the salt dissociates in water. Make sure to include correct phases. 2) Briefly explain which ions (Ba2+ or ClO- or both or maybe neither?) will hydrolyze. Write and balance any appropriate hydrolysis reaction(s). 3) The Solution is expected to be (Acidic,...
