Why is phosphoric acid called a triprotic acid?
Phosphoric acid is called a triprotic acid because it can donate three protons (H⁺ ions) when it is dissolved in water, leading to three dissociation steps and three corresponding Ka values.
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 Fewer steps are required to solve stoichiometry problems when?
Fewer steps are required to solve stoichiometry problems when the given quantities are well-balanced in terms of moles and when the molar ratios in the balanced chemical equation are easy to work with. This simplifies the calculations and reduces the need for additional conversions or adjustments.
Trihydroxybenzoic acid is a not so weak acid with an ionization constant ka equals 0.021 calculate the H plus and the pH of a 0.050 molar solution?
The ionization constant (Ka) for a weak acid can be used to calculate the concentration of H+ ions in solution. Since the acid is triprotic, the Ka value will be used three times to calculate the concentrations of all dissociation steps. The H+ concentration can then be converted to pH using the formula pH = -log[H+].
What difficulty arises is the precipitate is not allowed to settle completely from solution?
The difficulty that arises when the precipitate is not allowed to settle completely from solution is that the precipitate will not be as pure as it could be. If the precipitate is not allowed to settle, impurities will remain in the solution and will be present in the precipitate. This will result in a less pure product.
Why is phosphoric acid called a triprotic acid?
Phosphoric acid is called a triprotic acid because it can donate three protons (H⁺ ions) when it is dissolved in water, leading to three dissociation steps and three corresponding Ka values.
