- You have a clear colorless unknown solution with a group 1 cation. After adding some hydrochloric acid solution you obtain a white precipitate. Addition of ammonia causes the white precipitate to dissolve. Acidifying with nitric acid makes the precipitate reappear. Which cation do you suggest was in the unknown sample? Write the net ionic equation of any reaction that may occur (4P). 3. When testing for the presence of sulfate, what reagent is added to the solution? What final...

A calorimetry investigation is performed to determine the heat of neutralization when hydrochloric acid and sodium hydroxide solutions are mixed. Write the complete chemical equation for the reaction between hydrochloric acid and sodium hydroxide. Write the net ionic equation for the reaction between hydrochloric acid and sodium hydroxide. The procedure then calls for measuring 50.00 mL of each 0.10 molar solution. Why is it important to measure the volumes as accurately as possible? What is the most accurate measuring instrument...
