A 10. 0-mL sample of 1. 0 M NaHCO3 is titrated with 1. 0 M HCl (hydrochloric acid). Approximate the titration curve by plotting the following points: pH after 0 mL HCl added, pH after 1. 0 mL HCl added, pH after 9. 5 mL HCl added, pH after 10. 0 mL HCl added (equivalence point), pH after 10. 5 mL HCl added, and pH after 12. 0 mL HCl added
