Calcium Chloride (CaCl,) freely dissolves in water by the following equation. 2+ CaCl, (s) → Ca“ (aq) + 2 CI¯ (aq) If 50.0 mL of a 1.00 M solution of CaCl, (Solution A) is mixed with 105.0 mL of pure water to produce solution B and then 58.5 mL of solution B is mixed with 23.0 mL of solution A to give solution C, what is the concentration of CI (aq) in the final solution? (Solution C) Concentration of CI (aq)

A titration is a procedure for determining the concentration of a solution by allowing it to react with another solution of known concentration (called a standard solution). Acid-base reactions and oxidation- reduction reactions are used in titrations. For example, to find the concentration of an HCl solution (an acid), a standard solution of NaOH (a base) is added to a measured volume of HCI from a calibrated tube called a buret. An indicator is also present and it will change color when all the acid has reacted. Using the concentration of the standard solution and the volume dispensed, we can calculate molarity of the HCl solution. A volume of 90.0 mL of aqueous potassium hydroxide (KOH) was titrated against a standard solution of sulfuric acid (H₂SO4). What was the molarity of the KOH solution if 13.2 mL of 1.50 M H₂SO4 was needed? The equation is 2KOH(aq) + H₂SO4 (aq)→K₂SO4 (aq) + 2H₂O(1) Express your answer with the appropriate units. ► View Available Hint(s) molarity = Submit…

In a terrible accident, a solution consisting of 2.37 kg of nitric acid, HNO3, was spilled on the lab floor. Very quickly, you decide to throw 2.00 kg of sodium carbonate, Na2CO3, on the spilled acid. You then run out of the building due to the significant quantities of carbon dioxide that would form due to the reaction. As you stand outside, you wonder, "Did I add enough sodium carbonate to neutralize the acid?". a) Did you add enough sodium carbonate to neutralize the acid? Yes Ο No b) In the event that you did not add enough sodium carbonate, how much extra would be needed to completely neutralize the acid? If you have added enough, please enter a value of 0 (zero). Needed 0 c) In the event that you did add enough sodium carbonate, how much extra did you add? If you didn't add any extra, please enter a value of 0 (zero). Excess 09 g g

Sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 565 g NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq) solution.
