How to distinguish between naoh and nh4oh

Answer 1

Add Cacl2 to NaOH soln .
U will get a chalky white ppt of Ca(OH)2
Cacl2+2NaOH --> 2Nacl + Ca(OH)2{ppt}

But, of u add Cacl2 to NH4OH there is no ppt.{ No reaction}

Answer 2

Methods to distinguish between NaOH and $NH_4OH$.

• The given compound can be distinguished through a physical and chemical reaction.

Physical test:

• The physical properties used for differentiation are as follows:

1. NaOH is solid, white and crystalline whereas $NH_4OH$ is colorless liquid.

2. NaOH has no odor whereas $NH_4OH$ has a pungent smell.

Chemical test:

• The chemical reaction used for differentiation is that both substances reacts with calcium salt differently.
• In the case of NaOH, with calcium nitrate salt, it forms white precipitate due to the formation of calcium hydroxide.

• The chemical equation involved in the reaction is as follows:

$Ca(NO_3)_2+2NaOH\rightarrow 2NaNO_3+Ca(OH)_2$

• In the case of $NH_4OH$, with calcium nitrate salt, no such precipitate is formed.
• The chemical equation involved in the reaction is as follows:

$Ca(NO_3)_2+NH_4OH\rightarrow$ No reaction and no precipitation
