1) 68.1 mL of 5.2 M HCl solution is diluted to a volume of 555 mL. What is the molar concentration of the diluted solution? 2) Consider the following precipitation reaction: 2 AgNO3(aq) + MgCl2(aq) ---> 2 AgCl(s) + Mg(NO3)2(aq) How many grams of AgCl will theoretically form when 26mL of 0.75 M AgNO3 solution is added to 64 mL of a 0.25 M MgCl2 solution?
2 NaOH(aq) + H2C2O4 = 2H2O(s) Na2C2O4(aq) + 4 H2O(l) Calculate the molarity of an oxalic acid solution if it takes 34.0 mL of 0.200 M NaOH solution to consume the acid in a 25.0 mL sample of this oxalic acid solution.
Potassium hydrogen phthalate (KHP, HC8H4O4K) is used to standardize sodium hydroxide. If 25.00 mL of NaOH (aq) is required to titrate 0.8500 g KHP to the equivalence point, what is the concentration of the NaOH(aq)? (The molar mass of KHP = 204.2 g/mol) HC8H4O4-(aq) + OH-(aq) → C8H4O42-(aq) + H2O
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 (HCl) , 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) + CO2(9) The CO, gas produced is what makes you burp after drinking the solution. 2. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 250. mL of a 0.062 M HCl solution. What mass of NaHCO, would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits.
A 0.124 M NaOH(aq) solution was used to titrate 20.00 mL of an acetic acid (CH3COOH) solution that has an unknown concentration.

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 150.mL of a 0.053 M 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.

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 (HCI), 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 man suffering from indigestion can be considered to be 100. mL of a 0.029 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCl ? Be sure your answer has the correct number of significant digits. X Ś
