Which of the following are arranged in increasing order of solubilities ?

`CaCO_(3) lt KHCO_(3) lt NaHCO_(3)`

`NaHCO_(3) lt KHCO_(3) lt CaCO_(3)`

`KHCO_(3) lt NaHCO_(3) lt CaCO_(3)`

`CaCO_(3) lt NaHCO_(3) lt KHCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:

`CaCO_(3) lt NaHCO_(3) lt KHCO_(3)`
`KHCO_(3)` because of lasser lattrace energy it is more soluble in `H_(2)O` than `NaHCO_(3)` while `CaCO_(3)` is least soluble.

Which of the following has been arranged correctly in increasing order of acidic strength?

`HF lt HCI lt HBr lt H I`

`H_(3) PO_(2) lt H_(3) PO_(3) lt H_(3) PO_(4)`

`H_(3)PO_(4) lt H_(2)SO_(4) lt HCIO_(4)`

`NH_(3) lt PH_(3) lt AsH_(3) lt BiH_(3)`

The correct order of solubility is

`CaCO_(3)ltKHCO_(3)ltNaHCO_(3)`

`KHCO_(3)ltCaCO_(3)ltNaHCO_(3)`

`NaHCO_(3)ltCaCO_(3)ltKHCO_(3)`

`CaCO_(3)ltNaHCO_(3)ltKHCO_(3)`
