Classic S-shaped curve for HCl titrated with NaOH, with the equivalence point labeled at pH 7.
Acetic acid titrated with NaOH, highlighting the flat buffer region and half-equivalence point where pH equals pKa.
HCl titrated with ammonia, with the equivalence point below pH 7 due to the acidic nature of the conjugate acid.
A weak acid titration curve with both the equivalence point and half-equivalence point annotated with dashed lines and pH values.
A diprotic acid (such as carbonic acid) titration curve with two S-shaped inflections and two equivalence points.
Titration curve showing a shaded band for the indicator color-change range (e.g. phenolphthalein, pH 8.2-10) near the equivalence point.
Start with one of these examples, then adapt the subject, labels, data, or layout for your own use.
Classic S-shaped curve for HCl titrated with NaOH, with the equivalence point labeled at pH 7.
Create a labeled pH titration curve for a strong acid (HCl) titrated with a strong base (NaOH). Show an S-shaped curve with pH (0-14) on the y-axis and volume of NaOH (mL) on the x-axis. Label the equivalence point at pH 7 with a dashed line. Classic textbook style. White background.
Acetic acid titrated with NaOH, highlighting the flat buffer region and half-equivalence point where pH equals pKa.
Create a labeled pH titration curve for a weak acid (acetic acid) titrated with a strong base (NaOH). Draw the S-shaped curve with a visible flat buffer region, label the half-equivalence point where pH equals pKa (4.74), and mark the equivalence point. pH on the y-axis, volume of NaOH on the x-axis. White background.
HCl titrated with ammonia, with the equivalence point below pH 7 due to the acidic nature of the conjugate acid.
Create a labeled pH titration curve for a strong acid (HCl) titrated with a weak base (ammonia). Show the curve starting at low pH rising through an inflection point, with the equivalence point labeled below pH 7. pH on the y-axis, volume of ammonia on the x-axis. Classic style. White background.
A weak acid titration curve with both the equivalence point and half-equivalence point annotated with dashed lines and pH values.
Create a detailed labeled pH titration curve for a weak acid titrated with a strong base. Annotate both the half-equivalence point (with pH = pKa labeled) and the full equivalence point with dashed horizontal and vertical lines. Include tick marks, axis labels, and a clean S-shaped curve. White background.
A titration curve is a graph that tracks how the pH of a solution changes as a titrant is added during an acid-base titration. The x-axis shows the volume of titrant added (in milliliters) and the y-axis shows the resulting pH. The curve typically displays a characteristic S-shape with a steep inflection at the equivalence point, where the moles of acid exactly equal the moles of base. Figviz generates a clean, labeled titration curve from a plain description of your acid-base system, saving you from drawing and annotating by hand.
State the acid and base clearly and specify whether each is strong or weak. For weak acids, include the pKa if you know it so the half-equivalence point can be placed accurately. For polyprotic acids, mention the number of ionizable protons so all equivalence points appear. If you need an indicator range shown, name the indicator (for example phenolphthalein, pH 8.2-10, or methyl orange, pH 3.1-4.4). Always cross-check that the equivalence point pH matches your expected value before using the diagram for coursework.
