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.
How is the endpoint of a titration between H3PO4 and NaOH determined?
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 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.
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-.
Is conjugated base of H3PO4?
The conjugate base of H3PO4 is H2PO4-.

Why do we add H2So4 H3PO4 and di phenyl amine in the titration between k2Cr2O7 and mohr salt?
In the titration between potassium dichromate (K2Cr2O7) and Mohr's salt (ammonium iron(II) sulfate), sulfuric acid (H2SO4) is added to create an acidic environment, which is necessary for the complete reduction of Cr(VI) to Cr(III). Phosphoric acid (H3PO4) is sometimes included to stabilize the chromium species during the reaction. Diphenylamine serves as an indicator, changing color at the endpoint of the titration, allowing for accurate determination of the amount of dichromate present. Together, these reagents ensure a clear and effective titration process.
