Say you react 0.10 mol of Na2CO3 with 0.45 mol of acetic acid, producing sodium acetate,...
Sulfuric acid and sodium carbonate react to form carbon dioxide, water, and sodium sulfate as shown in the balanced equation below: H2SO4(aq) + Na2CO3(s) + CO2(g) + H2O(1) + Na2SO4(aq) In the presence of excess sulfuric acid, how many moles of CO2 would be released if you have 12.50 g of Na2CO3(s)? The molar mass of sodium carbonate is 106.0 g/mol, the molar mass of sulfuric acid is 98.08 g/mol, and the molar mass of carbon dioxide is 44.01 g/mol....
a buffer solution of pH =5.30 can be prepared by dissolving acetic acid and sodium acetate in water. How many moles of sodium acetate must be added to 1 L of 0.25 M acetic acid to prepare the buffer? Ka(CH3COOH)=1.8 x 10^-5
The acetic acid/acetate buffer system is a common buffer used in the laboratory. To prepare an acetic acid/acetate buffer, a technician mixes 32.6 mL of 0.0824 M acetic acid and 20.0 mL of 0.120 M sodium acetate in a 100 mL volumetric flask and then fills with water to the 100 mL mark. How many moles of acetic acid are present in this buffer? acetic acid: How many moles of sodium acetate are in the buffer? sodium acetate:
A buffer solution contains 0.05 mol of acetic acid and 0.065 mol of sodium acetate in 1.00-L. What is the pH of the buffer after the addition of 0.01 mol of HNO3? Ka(acetic acid) = 1.8 x 10^-5 Thank you!
A) A buffer solution contains 0.10 mol of acetic acid and 0.13 mol of sodium acetate in 1.00 L. What is the pH of the buffer after the addition of 3×10−2 mol of HNO3? Express your answer using two significant figures. C) Barium sulfate, BaSO4, is used in medical imaging of the gastrointestinal tract because it is opaque to X rays. A barium sulfate solution, sometimes called a cocktail, is ingested by the patient, whose stomach and intestines can then...
You are making a pH 5.0 buffer with acetic acid (pKa = 4.75) and sodium acetate. You want the total concentration of acetate ([acetic acid] + [sodium acetate] ), to be 0.50 M. What concentrations of acetic acid and sodium acetate do you use to make your buffer? acetic acid sodium acetate
A buffer solution with pH 5 is to be prepared by adding sodium acetate and acetic acid to enough water to make 1.00 L of solution. The pKa of acetic acid is 4.75. Given 0.600 mol of sodium acetate, what amount of acetic acid should be added to produce 1.00 L of a buffer solution at pH = 5.00?
An aqueous solution contains 0.25 M of acetic acid and 0.10 M of sodium acetate. If the pH of this solution was measured to be 2.50, calculate the pKa of acetic acid. a. pKa = 2.10 b. pKa = 3.20 c. pKa = 2.90 d. pKa = 3.80
A reaction between acetic acid and sodium hydroxide forms water and sodium acetate. Is this reaction endothermic or exothermic?
The reaction of sodium bicarbonate with acetic acid. If you have 0.03M sodium bicarbonate solution (you put 1g into 25 mL of seltzer water) and 0.03M vinegar solution (1.25mL into 25mL of seltzer water) how much carbon dioxide is generated in a 1:1, 2:1 and 1:2 ration of the reactants.
