White wash suspension, a saturated solution of ca(oh)2, has a ph of 12.37. what is ksp for ca(oh)2?
SSSSS [86.1K]

Find the pOH from pH

pH + pOH =14\\pOH= 14-pH = 14-12.37 = 1.63

The KSP value of ca(oh)^{2} is

ca(oh)^{2} -- > ca^{2} + (aq) +2OH^{-}    \\ksp = 4s^{3}

The value finally becomes,

ksp = 5.15 * x=10^{-5}

<h3>What are the properties of Saturated solution ?</h3>

A saturated solution is one that contains all of the solute that can possibly dissolve in it. The most sodium chloride that may dissolve in 100 g of water at 20°C is 36.0 g. Past that point, adding more NaCl won't cause it to dissolve because the solution is already saturated.

The solution reaches a point when it is saturated. This indicates that if you add more of the substance, it will stop dissolving and instead stay solid. The amount depends on how the solvent and solute interact molecularly.

How does a system at equilibrium respond to the addition of more reactant
grin007 [14]

Answer:

It favors the forward reaction.

Explanation:

According to Le Chatelier's Principle, when a system at equilibrium suffers a perturbation, the system will react in order to counteract the effect of such perturbation.

If more reactant is added, the system will try to decrease its concentration. It will do so by favoring the forward reaction, decreasing the concentration of the reactant  and increasing the concentration of the products, in order to re-establish the equilibrium.
