The aqueous solution is alkaline and is a strong base and weak acid salt. 1.Soda ash is mainly used in the production of glass, such as flat glass, bottle glass, optical glass and high-grade utensils. 2.It can be used to prepare sodium salts, metal carbonates, b...
H3PO4 has three acidic protons with the following Ka values: Ka1 = 7.1 x 10^{-3} Ka2 = 6.3 x 10^{-8} Ka3 = 4.5 x 10^{-13} If you have this acid in a solution with a pH=5 what is the predominate form of the compound in solution? CH...
NH3 is a weak base (Kb = 1.8\times10-5) and so the salt NH_4Cl acts as a weak acid. What is the pH of a solution that is 0.029 M in NH_4Cl at 25 C? NH3 is a weak base (Kb = 1.8\times10-5) and so the salt NH4Cl ac...
