Melissa Levy · Answer 1

1) Ammonium bromide is a salt of ammonium hydroxide and hydrogen bromide. The former is a weak base and the later is a strong acid so the salt will make acidic solution in water. It happens due to salt hydrolysis.

2) Potassium cyanide is salt of potassium hydroxide and hydrogen cyanide. The former is strong base and the later is weak acid so its salt will be basic in nature.

3) sodium chloride is a salt of sodium hydroxide and hydrogen chloride. The former is strong base and later is strong acid. So the salt is neutral.

4) Potassium iodide is a salt of potassium hydroxide and hydrogen iodide. The former is a strong base and the later is a strong acid. So the salt is neutral or a bit basic.
