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...

A) Consider the acid-base nature of the salt [(C2H5)3NH]CH3COO, when it is dissolved in water. (1) What are the acid-base properties of the cation, (C2H5)3NH+? _________acidic basic neutral (2) What are the acid-base properties of the anion, CH3COO-? _________acidic basic neutral (3) Would an aqueous solution of [(C2H5)3NH]CH3COO be acidic, basic or neutral? B )Consider the acid-base nature of barium hypochlorite, Ba(ClO)2, when it is dissolved in water. (1) What are the acid-base properties of the cation? _________acidic basic neutral...

Assuming equal concentrations, rank these solutions by pH. Almost. You've correctly placed the strong base at the top and the strong acid at the bottom. Now focus on the order of the three salts in the middle. A salt will be neutral if both its cation and anion are derived from strong acids and bases. A salt can act as a weak base if it contains the anion of a weak acid (i.e. any anion that is not the conjugate...
