Give one use with reason of I ] an aqueous solution of `NH_(3)` ii] liquefied `NH_(3)`.

An aqueous solution of NH_4F is …………….

Why is an aqueous solution of NH_4Cl acidic ?

The relative decreases in the vapour pressure of an aqueous solution containing 2 mol [Cu(NH_(3)_(3)Cl] in 3 mol H_(2)O is 0.50 . On reaction with AgNO_(3) , this solution will form

Arrange the following in the decreasing order of their basic strength in aqueous solutions : CH_(3)CSNH_(2),(CH_(3))_(2)NH, (CH_(3))_(3) N and NH_(3)

An aqueous solution of CoCl_(3).6NH_(3) is found to be a better conductor of electricity than an aqueous solution of CoCl_(3).4NH_(3) No ammonium ions are detected by addition of H_(2) SO_(4) to the solution of either of these compounds. Can you explain the difference in the conductivities of two solutions

The compound insoluble in aqueous NH_(3) is

Consider the following statement and select correct option: (I) K_(sp) of Fe(OH)_(3) in aqueous solution is 3.8xx10^(-38) at 298 K. The concentration of Fe^(+) will increase when [H^(+)] ion concentration decreases. (II) In a mixture of NH_(4)Cl and NH_(4)OH in water, a further amountof NH_(4)Cl is added. The pH of the mixture will decreases. (III) An aqueous solution of each of the following salt (NH_(4)I,HCOOK) will be basic, acidic respectively.

Assertion (A): Addtion of NH_(4)OH to an aqueous solution of BaCl_(2) in the presence of excess of NH_(4)Cl precipitates Ba(OH)_(2) . Reason (R ): Ba(OH)_(2) is insoluble in water.

NH_(4)^(+) ion in an aqueous solution will behave as :

Which of the following aqueous solution of cation(s) give(s) white ppt. with NaOH and NH_(4)OH solution and formed ppt. is/are further completely dissolved in one of the excess reagent?
