A sample of sodium carbonate unknown is dissolved in 50.0 mL of water. After performing experiment 3, student determines that the second equivalence point occurs at 32.86 mL of 0.1115 M HCl. What is the theoretical pH of the solution at the second equivalence point? Report your answer to two significant figures.

After performing Experiment 3, you have determined that your second equivalence point occurred after adding 42.50 mL of 0.1000 M HCl. Assuming that you dissolved your unknown sample in 150.00 mL of water, calculate the concentration of all species in solution AND the pH of the solution after 30.00 mL of HCl has been added? (Note: Kw = 1.00 x 10-14, Ka1= 4.44 x 10-7 and Ka2 = 4.69 x 10-11)

a. A student dissolves 1.1007 grams of their KHP unknown in 50.0 mL of water. The molarity of the student’s NaOH titrant is 0.0999 M. If it takes 40.25 mL of the sodium hydroxide titrant to reach the equivalence point, what is the wt% KHP (MW=204.23) in the unknown? b. If the student uses 55.0 mL of water instead of 50.0 mL to dissolve the unknown, what affect, if any, does this have on the calculated weight % of the...

A 0.4016 g sample of impure sodium carbonate (soda ash) is dissolved in 50 mL of distilled water. Phenolphthalein was added and 11.40 mL of 0.09942 M HCL was required to reach the first end point. Excess volume of HCL was added according to the lab procedure (if x is the amount of acid needed to complete the first titration, you will add a total of 2x + 10mL of acid to ensure excess). After boiling, the excess acid was...

An experiment was to identify the unknown solution as sodium carbonate or sodium bicarbonate by reacting it with HCl and taking pressure measurements. My chemical equations are: NaHCO3+HCl--->CO2+H2O+NaCl Na2CO3+2HCl--->CO2+H2O+2NaCl. The instructor said that it can be determined by looking at the chemical equation. My response was the pressure measurements were from the unknown were closer to sodium bicarbonate than sodium carbonate. Is this a correct assumption?
