• Assertion: Addition of silver ions to a mixture of aqueous sodium chloride and sodium bromide solution will first precipitate `AgBr` rather than `AgCl`. Reason : `K_(sp)` of `AgClltK_(sp)` of `AgBr`.A. Both A and R true and R is the correct explanation of AB. Both A and R are true but R is not a correct explanation of AC. A is true but R is falseD. A is false but R is true
• 100ml of 0.1M `H_(3)PO_(4)` is titrated with 0.05 M NaOH solution till 2nd equivalent point. Then, resultant solution was mixed with 10 ml of 0.5 MHCI solution `K_(1)=10^(-3)M` `K_(2)=10^(-8)M` `K_(3)=10^(-13)M` Solubility of compound `A(OH)_(2)` in final solution will be :A. `10_(10)M`B. `4xx10^(-10)M`C. `4xx10^(-22)M`D. `4xx10^(-14)M`
• Calculate degree of hydrolysis `K_(h)` and `pH` of `1M` urea hydtochloride solution in water `K_(b)` (Urea) `=1.5xx10^(-14)` at` 25^(@)C`.Consider urea as a monoacidic base.Take `log0.55=-0.26`
