The generic metal hydroxide M(OH)2 has Ksp = 7.25×10−12. (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.)

This is an incomplete question, here is a complete question.

The generic metal hydroxide M(OH)₂ has Ksp = 7.25 × 10⁻¹². (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?  Express your answer with the appropriate units.

Answer : The solubility of M(OH)₂ in pure water is,

Explanation :

The equilibrium chemical reaction will be:

The solubility constant expression for this reaction is:

Let the solubility be, 'x'

     x                 x                 2x

Now put all the given values in this expression, we get:

Thus, the solubility of M(OH)₂ in pure water is,

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
