Question

Calculate the expected initial pH for Buffer 1 and for Buffer 2.

Buffer 1:

Add 15 mL of 0.10 M HC₂H₃O₂ to a 25 mL volumetric flask using the syringe. Rinse the syringe with water.

Add 10 mL of 0.10 NaC₂H₃O₂ to the same volumetric flask using the syringe.

Buffer 2:

Add 10 mL of 0.50 M HC₂H₃O₂ to a 25 mL volumetric flask using the syringe. Rinse the syringe with water.

Add 15 mL of 0.50 M NaC₂H₃O₂ to the same volumetric flask using the syringe.

Answer 1

Answer #1

We know, Moles = Molarity (M) x Volume (V in L) Molarity of HC2H302= 0.100 M So Moles HC2H302 = 0.100 * 0.015 Volume of HC2H3

We know, Moles = Molarity (M) x Volume (V in L) Molarity of HC2H302= 0.500 M So Moles HC2H302 = 0.500 * 0.010 Volume of HC2H3
