A 1000 l sample of hcl gas at 25 degrees celsius and 732, Ask an Expert

Academics

A 1.000 L sample of HCl gas at 25 degrees Celsius and 732 mmHgwas absorbed completely in an aqueous solution that contained 6.954g of Na2CO3 and 250.0 g of water.
(a). What is the pH of the solution?

(b). What is the freezing point of the solution?

(c). What is the vapor pressure of the solution? (The vaporpressure of pure water at 25 degrees Celsius is 23.76 mmHg.) Consider the reaction that occurs on mixing 50.0 mL of 0.560 MNaHCO3 and 50.0 mL of 0.400 M NaOH at 25 degrees Celsius.

(a) Write a balanced net ionic equation for thereaction.

(b) What is the pH of the resulting solution?

(d) What is the final temperature of the solutoin to thenearest 0.1 degree Celsius? You may assume that all the heatliberated is absorbed by the solution, the mass of the solution is100.0 g, and its specific heat is 4.18 J/(gdegreeC).
