Question

Assertion : ${[A l {(H_{2} O)}_{6}]}^{3 +}$ is a stronger acid than ${[M g {(H_{2} O)}_{6}]}^{2 +}$ Reason: Size of ${[A l {(H_{2} O)}_{6}]}^{3 +}$ is smaller than ${[M g {(H_{2} O)}_{6}]}^{2 +}$ and possesses more effective nuclear charge.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Along a period size decreases and oxidation no of metal increases so ${[A l {(H_{2} O)}_{6}]}^{3 +}$ possess more effective nuclear charge due to smaller size of ${[A l {(H_{2} O)}_{6}]}^{3 +}$ and because of this it is a stronger acid.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica
