Potassium hydrogen phthalate (KHP) is soluble in water due to the presence of its polar functional groups, particularly the carboxylic acid and the potassium ion. These polar groups can form hydrogen bonds and ionic interactions with water molecules, facilitating its dissolution. Additionally, the overall ionic character of KHP allows it to dissociate in water, enhancing its solubility.
What else can I help you with?
Why does it not matter how much water you add when dissolving the acid (KHP) or when carrying out the titration?
The amount of water added during the dissolution of KHP or titration does not affect the final molarity because it only impacts the volume of the solution, not the amount of acid originally present. The concentration of the KHP solution is determined solely by the amount of the solute (KHP) dissolved, regardless of the total solution volume.
Why is KHP used as a primary standard?
KHP (potassium hydrogen phthalate) is used as a primary standard because it is a highly pure compound that can be accurately weighed and dissolved in water to give a known concentration, making it ideal for use in volumetric analysis to determine the concentration of other substances. Additionally, KHP is stable, has a high molecular weight for greater accuracy, and reacts stoichiometrically in a one-to-one ratio with bases, simplifying calculations.
A student weighed out 1.54g of khp. how many moles is this. how many moles of naoh will react with khp sample?
KHC8H4O4(aq) + NaOH(aq) --> KNaC8H4O4(aq) + H2O(l). The molar mass of KHP is approximately 204.22 g/mol. 1.54g of KHP is equivalent to 0.00754 mol of KHP. 1 mole of NaOH reacts per mole of KHP, so .00754 mol of NaOH are needed.
Did the volume of water you used to dissolve your KHP affect the results of your standardization?
Yes, the volume of water used can affect the concentration of KHP solution, which in turn can impact the accuracy of the standardization results. It is important to use a consistent volume of water to ensure reproducibility in the experiment.
