Titration Graph Explained. The shapes of titration curves for weak acids and bases. The titration curve demonstrating the pH change during the titration of the strong base with a weak acid shows that at the beginning the pH changes very slowly and gradually.
Step 2 is the loss of H from the less acidic NH 3 group. For the first part of the graph you have an excess of sodium hydroxide. This is useful because if you had HCl with an unknown concentration it can either scar you for life when you.
Titration of a Weak Acid with a Strong Base Introduction.
A titration can be performed in order to determine the concentration of an acid or a base by neutralizing it with another acid or base which you know the concentration of. Well take ethanoic acid and sodium hydroxide as typical of a weak acid and a strong base. The curves are usually plots of pH against the volume of titrant added or more correctly against the number of equivalents added per mole of the sample. Titration curves for weak acid v strong base.
