Consider the dissolution of ab(s): ab(s)⇌a+(aq)+b−(aq)le châtelier's principle tells us that an increase in either [a+] or [b−] will shift this equilibrium to the left, reducing the solubility of ab. in other words, ab is more soluble in pure water than in a solution that already contains a+ or b− ions. this is an example of the common-ion effect. the generic metal hydroxide m(oh)2 has ksp = 1.05×10−18. (note: in this particular problem, because of the magnitude of the ksp and the stoichiometry of the compound, the contribution of oh− from water can be ignored. however, this may not always be the case.)what is the solubility of m(oh)2 in pure water?

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
