When KBr is dissolved in water. `K^(+)` ions are

A

hydrated

B

hydrolysed

C

reduced

D

oxidised

Text Solution

Verified by Experts

The correct Answer is:
A
When KBr is dissolved in water , `K^(+)` ions are hydrated due to ionic nature, KBr is soluble in water.The solubility is due to the fact that `K^(+)` gets hydrated by `H_(2)O` molecule.The hydration energy compensates the lattice energy and hence solid breaks and dissolves.Hydration is an exothermic process.The energy of hydration of ions is known as hydration energy.

When common salt is dissolved in water

Henry's law constant for oxygen and nitrogen dissolved in water at 298 K are 2.0 xx 10^(9) Pa and 5.0 xx 10^(9) Pa , respectively . A sample of water at a temperature just above 273 K was equilibrated with air (20% oxygen and 80% nitrogen ) at 1 atm. The dissolved gas was separated from a sample of this water and the dried. Determine the composition of this gas.
