A student obtained a test tube with a suspension of white, slightly soluble calcium hydroxide in water. This system was at equilibrium as represented by the following equation:. Ca(OH)2(s)Ca2(aq)+ 20H(aq)
Write the equilibrium constant expression for this reaction.

K = [Ca²⁺] [OH¯]² / [Ca(OH)₂]

Explanation:

Equation for the reaction is given below:

Ca(OH)₂(s) —> Ca²⁺(aq) + 2OH¯(aq)

Equilibrium constant =?

Equilibrium constant (K) for a reaction is simply the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.

Thus, we can write the equilibrium constant (K) for the above reaction as follow:

Ca(OH)₂(s) —> Ca²⁺(aq) + 2OH¯(aq)

K = [Ca²⁺] [OH¯]² / [Ca(OH)₂]

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

idk what the question is about
