In a lab work, a teacher has given zinc salt solution for systematic analysis to two students studetn I added `NH_4Cl` followed by `NH_4OH` and student II added `NH_4OH` followed by `NH_4Cl` for the analyse of group III cations.
In the systematic analysis of group III - cations, what is the role of `NH_4Cl`?

In a lab work, a teacher has given zinc salt solution for systematic analysis to two students studetn I added NH_4Cl followed by NH_4OH and student II added NH_4OH followed by NH_4Cl for the analyse of group III cations. Predict the observation of each student. Give reasons for difference in observation in any.

In the detection of group III cations (eq. Al^(3+) ) in the qualitative analysis of salts, NH_(4)Cl is added before adding NH_(4)OH . This is meant

NH_4Cl is a molecule containing three types of bonds. Comment on this statement and justify your answer.

The pH of a salt solution depends on the hydrolysis of its ions Out of the following, which can produce an acidic solution in water? ( CH_3COONa , NH_4Cl , CH_3COONH_4 , NaCl)

the water solutions of the ionic compounds NaCl, CH_3COONa and NH_4Cl show different pH. Justify your answer.

[Co(NH_3)_5SO_4]Cl is an octahedral coordination compound write the formula of the ionisation isomer of the above compound

Write down the ionisation isomer of [Co(NH_3)_5Cl]SO_4

Write the expression for equilibrium constant for the decomposition of NH_4Cl by the reaction. NH_4Cl gives NH_3+HCl

When NH_4OH is added to copper sulphate solution, blue colour is obtained due to formation of
