The endpoint of a titration between H3PO4 (phosphoric acid) and NaOH (sodium hydroxide) is determined by using an indicator that changes color when the reaction is complete. This indicator helps to visually identify when the acid and base have reacted in the correct proportions, indicating the endpoint of the titration.

What is the procedure for conducting a titration using H3PO4 as the titrant?
To conduct a titration using H3PO4 as the titrant, first prepare a solution of H3PO4 of known concentration. Then, add the H3PO4 solution to the analyte solution (the solution being titrated) using a burette until the endpoint is reached. The endpoint is typically indicated by a color change or a sudden change in pH. Record the volume of H3PO4 solution used at the endpoint to calculate the concentration of the analyte.
How is the titration of H3PO4 with NaOH performed to determine the equivalence point?
During the titration of H3PO4 with NaOH to determine the equivalence point, a known volume of H3PO4 is gradually added to a solution of NaOH until the reaction reaches a neutral point. This is detected using an indicator that changes color at the equivalence point. The volume of NaOH required to reach this point is used to calculate the concentration of H3PO4.
What does the titration curve of H3PO4 reveal about its acid-base properties?
The titration curve of H3PO4 shows that it is a triprotic acid, meaning it can donate three protons (H ions) in a stepwise manner. The curve displays three distinct equivalence points, indicating the presence of three dissociation steps. This reveals that H3PO4 has multiple acidic hydrogen atoms with different strengths of acidity.
Is h3po4 ionic or covalent?
H3PO4, also known as phosphoric acid, is a covalent compound. It consists of covalent bonds between the atoms within the molecule.
What substances is the conjugate base H3PO4 H2PO4- or H2O?
In H2O the conjugate base is H2PO4-, being conjugated to the acid H3PO4. As well: H3PO4 is conjugated acid to the base H2PO4-.
