A 3.1 g sample of sodium hydrogen carbonate is added to a solution of acetic acid weighing 10.5 g. The two substances react, releasing carbon dioxide gas to the atmosphere. After the reaction, the contents of the reaction vessel weigh 11.6 g. What is the mass of carbon dioxide released during the reaction?
A 3.5 g sample of sodium hydrogen carbonate is added to a solution of acetic acid weighing 10.3 g. The two substances react, releasing carbon dioxide gas to the atmosphere. After the reaction, the contents of the reaction vessel weigh 12.5 g. What is the mass of carbon dioxide released during the reaction?
A 3.9 g sample of sodium hydrogen carbonate is added to a solution of acid weighing 10.4 . The two substances react, releasing carbon dioxide gas to the atmosphere. After the reaction, the contents of the reaction vessel weigh What is the mass of carbon dioxide released during the reaction? A 3.9 g sample of sodium hydrogen carbonate is added to a solution of acetic acid weighing 10.4 g. The two substances react, releasing carbon dioxide gas to the atmosphere....
5. (10 pts) Find pH of solution prepared by dissolving 1.0 g of sodium carbonate and 1.0 g of sodium hydrogen carbonate in enough water to make 100.0 mL solution. The base dissociation constant of carbonate ion is 1.8x10-4. Assume that hydrogen carbonate ion does not react with water.
Calculate the pH of the following solutions: 50.0 mL 0.10 M acetic acid + 1.0 mL 1.0 M HCl 50.0 mL 0.10 M acetic acid + 1.0 mL 1.0 M NaOH 50.0 mL 0.10 M sodium acetate + 1.0 mL 1.0 M HCl 50.0 mL 0.10 M sodium acetate + 1.0 mL 1.0 M NaOH 50.0 mL 0.10 M acetic acid/sodium acetate buffer 50.0 mL 0.10 M acetic acid/sodium acetate buffer + 1.0 mL 1.0 M HCl 50.0 mL 0.10...
Suppose you are given solutions of 1.00 M acetic acid and 1.00 M sodium acetate and are asked to make 100.00 mL of buffer at pH 5.00 using only these two solutions. What volume, in milliliters, of acid would you need? The pKa of acetic acid is 4.75
4. How much of (in mL) 0.15 M acetic acid (pKa 4.76) is needed to mix with 40 mL of 0.15 M sodium acetate to make a buffer of pH = 4.50 of 250 mL? (molar mass of acetic acid and sodium acetate are 60.0 g/mol and 82.0 g/ml, pKa of acetic acid is 4.76) (extra 10 pt)
Determine the pH of the following solutions a) You dissolve 2.75 g of acetic acid with enough water in a 500.0 mL volumetric flask. Ka of acetic acid = 1.76 x 10−5 b) You dissolve 3.20 g of sodium acetate with enough water in a 500.0 mL volumetric flask. c) You mix all of Solution A and B from above together into a larger beaker d) You add 3.50 mL of 1.0 M HCl into Solution C (buffer)
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 dissolve NaHCO3 neutralizes excess HCl through this reaction: HCI(aq) NaHCO3(aq) → NaCl(aq) + H,O() + CO2(g) The CO2 gas produced is what makes you burp after drinking the...
Suppose you want to make an acetic acid/acetate buffer to a pH of 5.00 using 10.0 mL of 1.00 M acetic acid solution. How many milliliters of 1.00 M sodium acetate solution would you need to add? The pKa for acetate buffer is 4.75.
