At 298 K temp. the K(sp) of Mg(OH)2 is ...

At 298 K temp. the `K_(sp)` of `Mg(OH)_2` is `1.8 xx 10^(-11)` . If the 0.1 M NaOH solution is added in it then what is the concentration of `Mg (OH)_2` ? Calculate its solubility in water.

Text Solution

Verified by Experts

solubility in water = `1.65xx10^(-4)` , solubility in NaOH = `1.8xx10^(-9)` M. Thus, adding NaOH solubility decreases
