- The molar solubility of barium phosphate in a 0.102 M barium nitrate solution is М.+ Titration of Weak Acid with Strong Base A titration involves adding a reactant of known quantity to a solution of an another reactant while monitoring the equilibrium concentrations. This allows one to determine the concentration of the second reactant. The equation for the reaction of a generic weak acid HA with a strong base is HA (aq) + OH (aq) →A (aq) + H₂O (1) A certain weak acid, HA, with a K, value of 5.61 x 106, is titrated with NaOH. Part A A solution is made by titrating 9.00 mmol (millimoles) of HA and 3.00 mmol of the strong base. What is the resulting pH?

- What volume of 0.250 M KCl(aq) will completely react with 50.0 mL of 0.115M Pb(NO3)2(aq)?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?
