(a)
Interpretation:
Molecular art for Na2S solution needs to be drawn.
Concept introduction:
Ionic compounds are held together by electrostatic attractions between the anion and the cation. When an ionic compound dissolves in water, it dissociates into its individual ions. The energy released when ions interact with water molecules should be equal to energy needed to break the electrostatic attractions between the ions for ionic compounds to be soluble in water.
(b)
Interpretation:
Molecular art for MgCl2 solution needs to be drawn.
Concept introduction:
Ionic compounds are held together by electrostatic attractions between the anion and the cation. When an ionic compound dissolves in water, it dissociates into its individual ions.

- ssume a highly magnified view of a solution of HCI that allows you to “see” the HCl. Draw this magnified view. If you dropped in a piece of magnesium, the magnesium would disappear, and hydrogen gas would he released. Represent this change using symbols for the elements, and write the balanced equation.arrow_forwardDescribe some physical and chemical properties of acids and bases. What is meant by a strong acid or base? Are strong acids and bases also strong electrolytes? Give several examples of strong acids and strong bases.arrow_forwardWhen 10. L of water is added to 3.0 L of 6.0 M H2SO4, what is the molarity of the resulting solution? Assume the volumes are additive.arrow_forward
- What is the molarity of a solution of sodium hydrogen sulfate that is prepared by dissolving 9.21 g NaHSO4 in enough water to form 2.00-L solution? What is the molarity of each ion in the solution?arrow_forwardEach box represents a tiny volume in an aqueous solution of an ionic compound. (For simplicity, water molecules are not shown.) Which box represents: (a) Na2CO3, (b) NH4NO3, (C) CaBr2? Explain your reasoning.arrow_forwardWrite a balanced equation for the reaction of hydroiodic acid, HI, with calcium hydroxide, Ca(OH)2. Then, write the balanced complete ionic equation and the net ionic equation for this neutralization reaction.arrow_forward
- You want to prepare a 1.0 mol/kg solution of ethyleneglycol, C2H4(OH)2, in water. Calculate the mass of ethylene glycol you would need to mix with 950. g water.arrow_forwardConsider a 13.0% solution of sulfuric acid, H2SO4,whose density is 1.090 g/mL. (a) Calculate the molarity of this solution. (b) To what volume should 100. mL of this solution bediluted to prepare a 1.10-M solution?arrow_forwardWhat volume of 0.250 M HCI is required to neutralize each of the following solutions? a. 25.0 mL of 0.103 M sodium hydroxide, NaOH b. 50.0 mL of 0.00501 M calcium hydroxide, Ca(OH)2 c. 20.0 mL of 0.226 M ammonia, NH3 d. 15.0 mL of 0.0991 M potassium hydroxide, KOHarrow_forward
