Question
Studying the Equilibrium of a Slightly soluble Salt, Mg(OH)_2 What is the initial color and appearance of the mixtures in Wells B-1 and B-2? If a precipitate is present note that fact, as well as the color of the precipitate. What color charge do you observe after adding concentrated HCl to Well B-1? What color change do you observe after adding Na_4 EDTA solution to Well B-2? What is the initial color and appearance of the mixtures in Wells B-3 and B-4? If a precipitate is present, note that fact and the color of the precipitate. What color change do you observe when you heat the mixture from Well B-3? What color change do you observe when you cool the pipet containing the heated mixture from Well B-4? What color change do you observe when you cool the pipet containing the heated mixture from Well B-3? What color change do you observe when you heat the pipet containing the cooled mixture from Well B-4? Write the net ionic equation for the equilibrium involving Mg(OH)_2 in this experiment. Predict the direction in which the equilibrium should shift when you add concentrated HCI to the mixture in Well B-1. Briefly explain. Briefly explain how your observations do or do not support your prediction in (24). Predict the direction in which the equilibrium should shift when you add Na_4EDTA solution to the mixture in Wells B-2. Briefly explain. Briefly explain how your observations do or do not support your prediction in (26). Based on your observations of heating the you mixture from Well B-3, is the forward reaction endothermic or exothermic? Briefly explain. Write the net ionic equation for the equilibrium but include heat in the equation this time.Explanation / Answer
Following is the Solution to the first question (i.e. Question - 15 ) of the given Question Set....
Answer:
Mixture of Mg(OH)2 with water, should be Clear and almost Transparent in colour...... And, since Mg(OH)2 is slightly soluble, I think its precipitate should be White in color....
