Kw = ka . @ A 0.180 M solution of a weak acid (HA) has a pH of 2.96. Ka = [HOBr] [H+ ][OBr ] . Calculate the pH of a 0.17 M solution of hypochlorous acid, HClO. Find the value of pH for the acid. Q. NH3, A:When valence electrons present in atoms of a compound are represented by dots in a structure then it, Q:Lithium dihydrogen borate (LIH2BO3) is the lithium salt Enter your answer in scientific notation. A:The relation between dissociation constant for acid, base and water is given as follows, CO2 + O2- --> CO3^2- Hypobromous acid is a weak acid (Ka = 2.8 * 10-9 M). A strong acid ionizes completely in an aqueous solution by losing one proton, according to the following equation: where HA is a protonated acid, H + is the free acidic proton, and A - is the conjugate base. Given that Ka for HBrO is 2.8 x 10-9 at 25 degree C, what is the value of Kb for BrO- at 25 C? The acid dissociation constant Ka of hydrocyanic acid HCN is 6.21010.
