How could you distinguish solution of sodium chloride (table salt) from a solution of sodium iodide (a poison) using an AgNO3 solution? Show reactions. Express your answers as balanced chemical equations. Identify all of the phases in your answer. Seperate the two equations by a comma.

As shown in the following Figure, an aqueous solution of Nal is poured into an aqueous solution of Pb(NO3)2 which results in the formation of a yellow precipitate. Assuming stoichiometric amounts of Nal and Pb(NO3)2 are reacted, give the chemical formula of the yellow precipitate and the chemical formula of all molecules and/or ions that are present in the solution (You may use the solubility matrix to answer this question). (b)

You have 1g of lithium orotate with a molar mass of 163.03. You wish to make 100ml of 5mM lithium orotate in aqueous solution. How many grams of lithium orotate would you need?

A 0.3240 g sample of potassium hydrogen phthalate is dissolved in 100.0 mL of water. If 26.79 mL of sodium hydroxide solution are required to reach the equivalence point, what is the molarity of the sodium hydroxide solution? Be sure to report your answer with the correct units and number of significant figures.

A bottle of anhydrous copper(II) sulfate was accidentally left uncapped for an afternoon, allowing it to pick up water from the environment. To determine the degree to which the compound was hydrated, a sample was analyzed. The initial weight of the partially hydrated copper(II) sulfate was 9.782. After drying to constant weight, the weight was 7.232. How may waters of hydration are present?

How do we solve this with dimensional analysis?

Enter the net ionic equation representing solid chromium (III) hydroxide reacting with nitrous acid. Express your answer as a balanced net ionic equation. Identify all of the phases in your answer. ΑΣφ ? DA chemical reaction does not occur for this question.

The solution was prepared by adding 150 g of sodium hydroxide to 150 g of water, giving a total weight of 300 g. Density of the solution is 1.53 g/mL What is the molarity of the solution? 2. Pause the Student Protocol video at 1 minute 39 seconds. Now use your molarity in the dilution equation to calculate the number of mL you will need to dilute to make 500 mL of a 0.10 M sodium hydroxide solution.

You wish to make a 0.382 M hydrochloric acid solution from a stock solution of 12.0 M hydrochloric acid. How much concentrated acid must you add to obtain a total volume of 175 mL of the dilute solution?

How many grams of NaOH are there in 333. mL of a 0.90 M NaOH solution?
