Concentration is measured by molarity (M), or moles per liter. Brackets are also used to symbolize molarity. For example, if 0.6 moles of HNO3 are dissolved in a liter of water, you would say [HNO3] = 0.6 M.   Because HNO3 is a strong acid, it dissociates almost completely in water. That means the concentration of H+ is very nearly equal to that of HNO3. What is [H+] if [HNO3] is 0.01 M?      The pH of a solution is equal to the negative log of H+ concentration: pH = –log[H+]  What is the pH of this solution?      What is the pH of a 0.6 M HNO3 solution?

using this balanced equation CaCO3(s) + 2 HCl(aq) ----> H2O(l) + CO2(g) + CaCl2(aq) Stomach acid is 0.100 M HCL. An active ingreident found in antacids such as Alka Seltzer is calcium carbonate, CaCO3. Calculate grams of calcium carbonate needed to react with 80 ml of stomach acid.

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 (HC1), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HC1 through this reaction: HCl(aq) + NaHCO3(aq) NaCl(aq) + H₂O(1) + 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 150. mL of a 0.010 M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCl ? Round your answer to 2 significant digits. ■ x10 ×
