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.
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 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 is the percent composition of phosphoric acid in the formula H3PO4?
The percent composition of phosphoric acid (H3PO4) can be calculated as follows: Percentage of hydrogen (H): (3 x atomic mass of H) / molar mass of H3PO4 Percentage of phosphorus (P): (atomic mass of P) / molar mass of H3PO4 Percentage of oxygen (O): (4 x atomic mass of O) / molar mass of H3PO4 These values can be used to determine the percent composition of each element in phosphoric acid.

What mass of each product results if 750 mL of 6.00 M H3PO4 reacts according to the equation H3PO4+Ca(OH)2=Ca(PO4)2+H2O?
To solve this problem, you will need to use the balanced chemical equation provided to determine the mole ratios between the reactants and products. First, convert the volume of H3PO4 to liters by dividing by 1000 mL/L: 750 mL H3PO4 / 1000 mL/L = 0.750 L H3PO4 Next, convert the concentration of H3PO4 to moles/L: 6.00 M H3PO4 = 6.00 mol/L H3PO4 Now, use the volume and concentration to calculate the number of moles of H3PO4: 0.750 L H3PO4 * 6.00 mol/L H3PO4 = 4.50 mol H3PO4 Since the chemical equation shows a 1:1 mole ratio between H3PO4 and Ca(OH)2, there must be 4.50 mol Ca(OH)2 as well. To determine the mass of each product, you will need to know the molar masses of each compound. The molar mass of H3PO4 is 98.00 g/mol, and the molar mass of Ca(PO4)2 is 212.09 g/mol. Therefore, the mass of H3PO4 produced in the reaction is: 4.50 mol H3PO4 * 98.00 g/mol = 434.00 g H3PO4 And the mass of Ca(PO4)2 produced in the reaction is: 4.50 mol Ca(PO4)2 * 212.09 g/mol = 953.41 g Ca(PO4)2 These are the masses of each product that would be produced if 750 mL of 6.00 M H3PO4 reacts according to the given chemical equation.
