The list is: Fe (NO3)3 NaClO NaNO3 CH3NH3CN and CH3NH3Cl So salts that result from the reaction of a weak acid and a strong base are basic, and weak bases with strong acids will be acidic. The second equation is for some generic base, B, with some generic acid, HX. Has anything like that creepy happened to you when someone you know account got hacked and knew someone else was using it? Since the are equal the solution will be neutral and the pH close to 7. Made from an acid and a base, salt can react with water and produce acidic, basic, or neutral solutions. Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt. How can you do a cross product on a TI-89 calculator? and A when the acid ionizes in water; Figure 1 lists several strong acids.
