Write Balanced net ionic equations for the reactions between (if no reaction put NR): Show state of of products "l", "aq", "s" or "g" a) NH_4^+ (aq) + OH^- (aq) rightarrow b) Ca^2+ (aq) + CO^2+_3 (aq) rightarrow c) K^+ (aq) + SO^2-_4 (aq) rightarrow d) BaCO_3 + H^+ (aq) (excess) rightarrow e) Fe^3+ (aq) + OH^- (aq) rightarrow Calculate pH of a buffer solution prepared by mixing 1000 0mL of 0.100 M NH_3 with 10.800 g of solid NH_4Cl (molar mass-53.50 g/mol). Calculate pH of the buffer from problem 2 after addition to buffer 2.00g of HCl(g) (molar mass-36.50g/mol) Net ionic equation must be given. 4. 0 120M solution of monohydroxo base has the pH vaiue of 10.10. Calculate the value of K_b (base ionization constant).
