ANSWER ALL OF THESE SHORT QUESTIONS Which of the following ions is formed when an acid is dissolved in a solution? H + O − OH − SO 4 2+ is the molarity of a solution prepared by dissolving 20.0 grams of NaOH in sufficient water to make a solution with a total volume of 2.40 liters? 0.120 M NaOH 0.208 M NaOH 0.416 M NaOH 0.833 M NaOH How many liters of 3.0 M NaOH solution will react with 2.4 mol H 2 SO 4 ? (Remember to balance the equation.) H 2 SO 4 + NaOH → Na 2 SO 4 + H 2 O 1.2 L 1.6 L 2.4 L 2.8 L happens to water when it freezes? It expands. It forms vapor. Its density increases. Its composition changes. A 10 M concentrated stock solution of NaCl was used to prepare 5 liters of diluted 1 M solution. Which of the following statements is true about the process used to achieve this required dilution? The volume of stock solution used was less than 0.4 liters. The volume of stock solution used was more than 5 liters. The volume of the solvent used was less than 0.4 liters. The volume of the solvent used was less than 5 liters.
