Then the student added a few drops of an unknown solution to the test tube and observed cloudiness in the solutions as shown in figure 2. On the basis of this information and the equilibrium represented above, which of the following is most likely the identity of the reagent added from the dropper.
The concentration of hydrogen peroxide in a solution is determined by titrating it with a 0.1217 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnO4 (aq) + 5H₂O₂ (aq) + 6H3O+ (aq) → 2Mn²+ (aq) +50₂ (1) + 14H₂O(1) In one experiment, 19.09 mL of the 0.1217 M permanganate solution is required to react completely with 40.00 mL of the hydrogen peroxide solution. Calculate the concentration of the hydrogen peroxide solution. Concentration = M
Sodium hydrogen carbonate NaHCO3, 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 HCl, which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl(aq)+NaHCO3(aq)→NaCl(aq)+H2O(l)+CO2(g) The CO2 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 0.027M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl? Be sure your answer has the correct number of significant digits.
