Question

50 ml of 2 N Acetic Acid mixed with 10 ml of 1 N Sodium Acetate solution will have an approximate pH of (Ka=10^-5)

options are

1) 4. 2)5. 3)6. 4)7.

Answer 1

Answer:

Complete answer:

Let's first calculate the concentration of acetic acid and sodium acetate, Here, the Total volume is V1=50mL+10mL=60mL as acetic acid and sodium acetate-mix together to form a buffer. Therefore the pH of the acetic acid buffer is 4.0.
