Question

Both ammonium and sodium hydroxide are used in analytical chemistry for identifying __________of salts.

Answer 1

Answer:

NH4OH and NaOH can be distinguished by using calcium salts. For example on adding NaOH to Ca(NO3)2, Ca(OH)2 is obtained as white precipitate which is sparingly soluble in excess of NaOH.

Answer 2

• Both ammonium hydroxide and sodium hydroxide are strong base.
• In analytical chemistry these strong bases are used to identify metal cation or anion because both of these bases give characteristics test of metal cation or anion.
