Explanation:
Calculate the solubility of Au(OH)3 in water
Answer:
--Acid is the substance when dissolved in water, increases the concentration of H+ ions.
--Such compound whose chemical formula begins with H, for example HCl (Hydrochloric acid), H3BO3 (Boric acid), CH2O3 (Carbonic
acid). Although CH3COOH (Acetic acid) is an exception.
--Its less than 7.
--Bases are the proton acceptor.
--Such compounds whose chemical formula ends with OH, for example KOH (Potassium hydroxide), NaOH (Sodium hydroxide).
--Its greater than 7.
Explanation:
Magnesium has 2 valence electrons and 12 electrons.

Answer:
the solubility of the ionic solid decreases
Explanation:
If a salt MX is added to an aqueous solution containing the solute AX, the X^- ion is common to both of the salts. The presence of X^- in the solution will suppress the dissolution of AX compared to the solubility of AX in pure water. This observation is known as common ion effect in chemistry.
The origin of common ion effect is based on Le Chatelier's principle. The addition of a solute will drive the equilibrium position towards the left hand side.
Answer:
unsaturated solution
Explanation:
Given: Epsom salts have a solubility 26.2 grams.
By definition,Solubility is the maximum amount of solute that can be dissolved in 100 g of water.
A solution is called saturated solution when the concentration of solute becomes equal to its solubility.
If the concentration of solute is less than solubility it is called unsaturated solution.
In this case: solubility is 26.2 grams.
If we dissolve 26 grams of Epsom salt in 100 g of water , concentration of solute is less than the solubility(26.2 g in 100 g of water) , hence it is an unsaturated solution.
