A 100 mL sample contains Na2CO3 and NaOH. A 25 mL aliquot was taken and phenolphthalein was added as indicator into the solution. The sample solution was titrated with 13.0 mL of 0.10 M HCI. After the disappearance of the pink color, methyl orange was added and the sample solution was titrated with 4.0 mL of 0.10 M HCI. Calculate the amounts of Na2CO3 and NaOH in the sample as mg/100 mL. (write all chemical reactions, Na:23, C:12, 0:16, H:1 g/mol).

I placed 10 drops of 1.0 M CoCl2 in a test tube. I then added drops on concentrated HCl. The color changed from burgandy to violet with just 5 drops of HCl. Then I added a few drops of water and the color changed back to burgandy. What is the reason for the change back to burgandy?
250 ml volume of a mixture of 0.8g of NaHCO3 and 0.2g of NaOH in water. Take 50 ml of this mixture and titrate with o.1 N of HCI. Calculate the volume of acid?
A sample of antacid tablet that contains NaHCO3 is analyzed in the lab. The student dissolves 1.50g tablet in 35.0 mL of HCl solution containing 0.0300 mole of HCl. The back-titration of the excess HCl require 10.5 mL of 2.05M NaOH solution. 1) If that tablet label showed that each tablet contains 0.950 gram of NaHCO3. Determine the percent error in the student experiment. 2) Calculate the mass percent of the NaHCO3 in the tablet.

1.) A 100mL sample is taken to determine the alkalinity in a 1 liter water sample and titrated with 0.15M HCl. As a result of the titration, 150mL of acid is spent with the methyl orange indicator, while 40mL of acid is spent with the phenolphthalein indicator. Calculate the alkalinity in the sample and how many grams they are in terms of sodium salts. (Na: 23g / mol, O: 16g / mol, C: 12g / mol, H: 1g / mol)

An 20.00 mL unknown solution required two indicators for titration. The first indicator reaches its endpoint upon the addition of 20.00 mL 0.1000 M hydrochloric acid solution, while the second titrant reaches it endpoint upon the addition of exactly the same volume of the acid. Analyze the problem and identify the concentration of the base in the solution. O 0.1000 M Na2CO3 O 0.1000 M NaHCO3 O 0.1000 M NaHCO3: 0.1000 M NAOH O 0.1000 M Na2CO3 0.1000 M NaOH
7. A solution was made by mixing 50.0 mL of 0.750 M HCN with 25.0 mL of water. What is the pH of this solution? The pka of HCN = 9.31. 8. One of the compounds featured on the TV series "Breaking Bad" was hydrofluoric acid (HF), pKa = 3.14. a) A solution of HF has a pH = 1.77. What was the initial [HF] for this solution in mol L-1? b) What is the equilibrium concentration of F in this solution in mol L-1? c) What is the percent ionization of HF in this solution?
In the titration of a solution of weak monoprotic acid with a 0.1375 M solution of NaOH, the pH half way to the equivalence point was 4.46 . In the titration of a second solution of the same acid, exactly twice as much of a 0.1375 M solution of NaOH was needed to reach the equivalence point. What was the pH half way to the equivalence point in this titration?
Please answer this
True or false? The pH of the titration of a weak base with a strong acid at equivalence point is higher than 7.00 and the solution is basic.
