12. Calculate the pH and the concentration of all species in solution of 0.33 M K2CO3....
Calculate the pH and the concentrations of all species present (H2CO3, HCO3 – , CO3 2– , H3O + , and OH– ) in a 0.0037 M M carbonic acid solution. Ka1 = 4.3 × 10–7 ; Ka2 = 5.6 × 10–11
Find the concentration of all species in solution for a 0.10 M solution of H3PO4, a triprotic weak acid. acetic acid: Ka = 1.7 x 10-5 ammonia: Kb = 1.8 x 10-5 carbonic acid: Ka1 = 4.3 x 10-7; Ka2 = 4.8 x 10-11
Calculate the concentration of all species in a 0.165 M solution of H2CO3 (Ka1 is 4.3×10−7 and Ka2 is 5.6×10−11).
Calculate the pH and concentration of species present in a polyprotic acid solution.For a 3.44×10-3 M solution ofH2CO3, calculate both the pH and the CO32- ion concentration.H2CO3 + H2O → H3O+ +HCO3-Ka1 = 4.2×10-7HCO3- + H2O → H3O+ +CO32-Ka2 = 4.8×10-11pH =[CO32-] =
