Given/Details below: Before a strong base is added: pH is between 2 & 3 After 10.00mL strong base is added : pH is between 3 & 4 After 25 mL strong base is added: pH is between 3 & 4 After 40 mL strong base is added: pH is between 4 & 5 After 50 mL strong base is added: pH is between 9 & 10 After 60 mL strong base is added: pH is between 11 & 12 Give the name of another weak acid that will have a similar titration curve. Briefly explain the reason for the similarity. (Picture shown is the titration curve of formic acid and strong base)
