4. Your laboratory supervisor has created a buffer by adding 25.0 g HC,H,O, and 30.0 g of NaC,H,O, to enough water to form a 250 mL solution. The K of HC,H,O, is 6.76 x 104 The laboratory supervisor then instructs you to determine the pH of the buffer. (1 point for the correct molarity of HC,H,O, one point for the correct molarity of NaC,H,Og, and one point for the correct pH)
