Compare the solubility of mn(oh)2 (ksp = 1.6x10-13)in the following solutions: pure water, a solution buffered to be ph = 6.5 a solution buffered to be ph = 3.5 compare the solubility of mn(oh)2 (ksp = 1.6x10-13)in the following solutions: pure water, a solution buffered to be ph = 6.5 a solution buffered to be ph = 3.5 pure water > ph 3.5 > ph 6.5 (least soluble) ph 3.5 > ph 6.5 > pure water (least soluble) ph 3.5 > pure water > ph 6.5 (least soluble) pure water > ph 6.5 > ph 3.5 (least soluble) ph 6.5 > ph 3.5 > pure water (least soluble)

The order will be:

pH 3.5 > pH 6.5 > pH 7

Explanation:

The solubility equation for Mn(OH)₂ is:

As per the reaction, Mn(OH)₂ is giving hydroxide ions

The given conditions are

a) Pure water = here the pH of water is 7.

[OH⁻] = 10⁻⁷ M

b) pH = 6.5

pOH = 7.5

[OH⁻] = 3.16 X 10⁻⁸ M

c) pH = 3.5

pOH = 10.5

[OH⁻] =3.16 X  10⁻¹¹ M

Thus from the three solutions and water the maximum concentration of hdyroxide ion is in pure water, hence the Mn(OH)₂ will be least soluble in it.

More the concentration of hydroxide, lesser the solubility of Mn(OH)₂

Order will be

pH 3.5 > pH 6.5 > pH 7

i think a, hope it .

explanation:

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
