100.0 mL of 3.00 M HCl (in water) is added to 50.0 mL of 5.00 M NaOH in a beaker. What is present in the beaker?
To a 100.0 mL volumetric flask were added 25.0 mL of 0.74 M KH2PO4 and 50.0 mL of 0.35 M Li2HPO4. After the flask was filled to the calibration line, a 3.75 mL sample of 2.5 M sodium hydroxide was then added. Ka1= 6.4x10-8 and Ka2= 4.8x10-13 What is the pH of the initial solution before the sodium hydroxide was added? What is the pH of the final solution after the addition of the sodium hydroxide? Is the solution still...
