Sodium hydrogen carbonate (NaHCO,), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) , which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) + NaHCO,(aq) NaCl(aq) + H,O(1) + CO,(g) The CO, gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 50. mL of a 0.019M HCl solution. What mass of NaHCO, would she need to ingest to neutralize this much HCI ? Be sure your answer has the correct number of significant digits. 10 Submit Assignment 2020 McGraw-Hill Education.

The traditional method of analysis for the amount of chloride ion present in a sample is to dissolve the sample in water and then slowly to add a solution of silver nitrate. Silver chloride is very insoluble in water, and by adding silver nitrate, it is possible effectively to remove all chloride ion from the sample. Ag+(aq) + Cl-(aq) → AgCl(s) Suppose a 1.515 g sample is known to contain 27.5% chloride ion by mass. What mass of silver nitrate must be used to completely precipitate the chloride ion from the sample?
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.

You have a solution that is either CuCl2 (aq) or Cu(NO3)2 (aq). You add some KOH (aq) and a solid precipitate is formed. Does this test allow you to determine the contents of your solution? If so, how? If not, what other test could you perform that would give you the information that you need? Please explain.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe(s)+CuSO4(aq) ----------> Cu(s)+FeSO4(aq) Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 500.mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 104.mg.Calculate the original concentration of copper(II) sulfate in the sample. Round your answer to 3 significant digits. _______________g/L
