What the situation 

1-Calculate the pH at 0, 10.0, 25.0, 50.0, and 60.0mL titrant in the titration of 50.0mL of 0.100 M H,SO4 with 0.100 M NaOH and draw the titration curve. 2-A 0.2000-g sample containing urea is analyzed by the Kjeldahl method. The ammonia is collected in 50.00mL of 0.05000 M H,SO4, and the excess acid is back-titrated with 0.05000 M NaOH, a procedure requiring 3.40 mL. Calculate the percent urea in the sample. 3-The pKa of finalic acid is 6.50, What is the pH of an equimolar solution of finalic acid and sodium finalate? Assume that both solutions are at 0. 1 M. 4-Calculate pCl for the titration of 100.0 mL of 0.1000 M CI with 0.1000 M AGNO; for the addition of 0.00 and 20.00 mL AgNO3.
