Question

What are the 4 titration curves and what are their properties such as drawings?

Answer 1

Titrations curves describes how pH changes during acid -base titrations

1) Titration curve for strong acid vs. strong base (HCl vs.NaoH, running Hcl into NaoH)

In this Curve begins at high pH, a basic pH and ends at low pH, an acidic pH, rapid changes in pH near equvivalence point.pH=7 at equivalent point.

2) Titration curve for strong acid vs weak base (Hcl vs.NH_3, running Hcl into ammonia)

In this Curve begins at pH=9.5, a basic pH and ends at low pH, an acidic pH, rapid changes in pH near equvivalence point.pH<7 at equivalent point.

3) Titration curve for Weak acid vs. strong base (CH₃COOH vs NaOH, running acetic acid into NaOH)

In this Curve begins at high pH, a basic pH and ends at low pH (pH=4.0, an acidic pH, rapid changes in pH near equvivalence point.pH>7 at equivalent point.

4) Titration curve for Weak acid vs. strong base (CH₃COOH vs NH₃, running acetic acid into ammonia)

In this Curve begins at pH=9.5, a basic pH and ends at low pH (pH=4.0), an acidic pH, no rapid changes in pH at equivalent point.
