Question

© KOH ; Al(oH)3 Mg(OH) Rb(OH) increasing order arrange
​

Answer 1

Answer:

here is your ans mate ⤵️⤵️

For chloride ions, the normality is 2N because 1M of calcium chloride yields 2M of chloride ions. For calcium, the valency is +2. So it is like calcium can take place of two hydrogen ions. Therefore, its normality is also 2.

Answer 2

Increasing order arrange

Explanation:

The correct order of basic nature of the given compounds is:

$RbOH > KOH > Mg(OH)_{2} > Al(OH)_{3}$

• Basicity of the compound is the extent of how easily it can release hydroxide ion in the solution.
• The ease to liberate the hydroxyl group depends on the size of central atom.
• When the size of the central electropositive atom is small, it will hold the hydroxide ion more strongly, the bond between central atom and hydroxyl group will be more strong.
• As the size of the central atom increases, the hold over hydroxyl group loosens, the bond is weakened. This causes easy liberation of hydroxide ion.
• Therefore, Rb being bigger in size is most basic among the given compounds whereas Al being smaller is least basic.
