<span>When calcium hydroxide dissolves, it dissociates into
Ca(OH)2 = Ca2+ and 2OH-
Let's assign the variable X for the solubility of Ca2+ and OH
I.e Ca2+ = X and 2OH- = 2X
Then Ksp = [Ca2+][OH-]^2
So we have (X) (2X)^2 = 5.02 * 10^(-6)
4X^3 = 5.02 * 10 ^(-6)
X^3 = 5.02 * 10^(-6) / 4
X^3 = 0.003110
X = 0.1459</span>
It isn't a materialistic object.
2HCO3 - + Ca2+ CaCO3 + CO2 + H2O Bicarbonate (HCO3-) combines with calcium ions in the water to make calcium carbonate (CaCO3, limestone). This process can occur both within organisms such as corals or as a simple chemical reaction in the water itself.
Answer:
The solution will turn red.
Explanation:
HC₁₄H₁₄SO₃ + H₂O ⇌ HC₁₄H₁₄SO₃⁻ +H₃O⁺
(red) (yellow)
Methyl orange is a weak acid in which the ionized and unionized forms are distinct colours and are in equilibrium with each other,
At about pH 3.4, the two the forms are present in equal amounts, and the indicator colour is orange.
If you add more acid, you are disturbing the equilibrium.
According to Le Châtelier's Principle, when you apply a stress to a system at equilibrium, it will respond in such a way as to relieve the stress.
The system will try to get rid of the added acid, so the position of equilibrium will move to the left.
More of the unionized molecules will form, so the solution will turn red.
