1.	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.
Answer» Solution :solubility in WATER = `1.65xx10^(-4)` , solubility in NAOH = `1.8xx10^(-9)` M. THUS, adding NaOH solubility decreases
