What is the molarity of a NaOH solution if 28.50 mL are needed to titrated a 0.7154 g sample of KHP?
Since KHP is an unknown (name for a) chemical compound the molarity can not be calculated by lack of data.The molar mass (m) of KHP ANDthe number (n) of H+ per mol KHP (maybe 1 when monoprotic?) is necessary for calculation, according to this formula:(M*V)NaOH = (n*mass/m)KHPso:[OH-] (mol.L-1) * 0.02850 (L NaOH sol'n) = n (mol H+.mol-1 KHP) * 0.7154 (g KHP) / m (g.mol-1 KHP)
What is the shortened structural formula for KHP?
molar mass of KHP is 204.2g/mole. the formula for KHP is C8H5O4K therefore, (12.01*8)+(1.008*5)+(16*4)+39.1 = 204.2g/mol
How many grams of KHP will be required to titrate 50 mL of 12 M NaOh solution?
To determine the grams of KHP required, you first need to calculate the number of moles of NaOH present in the 50 mL solution. Then, using the balanced chemical equation of the titration between NaOH and KHP, you can find the mole ratio. From the mole ratio and the moles of NaOH, you can calculate the moles of KHP needed and then convert that to grams of KHP.
What is the correct abbreviation for potassium hydrogen pthalate?
KHP
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.
What is it about the structure of khp that tells you it is a weak acid?
The structure of KHP (potassium hydrogen phthalate) contains a carboxylic acid functional group (COOH), which is a characteristic of weak acids. Weak acids only partially dissociate in solution, releasing fewer protons compared to strong acids. In the case of KHP, only a fraction of the molecules donate protons to the solution, resulting in a weak acidic behavior.
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.

How do you standardize 1N H2SO4 with a KHP?
To standardize 1N H2SO4 with KHP, you would first prepare a solution of KHP of known concentration. Then, titrate the KHP solution with the 1N H2SO4 solution until the endpoint is reached. The volume of H2SO4 used in the titration can then be used to calculate the exact concentration of the H2SO4 solution.
What is the shortened structural formula for KHP?
molar mass of KHP is 204.2g/mole. the formula for KHP is C8H5O4K therefore, (12.01*8)+(1.008*5)+(16*4)+39.1 = 204.2g/mol
How many units per gram in KHP?
The molar mass of potassium hydrogen phthalate (KHP) is approximately 204.23 g/mol. Therefore, in 1 gram of KHP, there is approximately 0.00489 moles (1/204.23).
What is the molarmass of KHP?
The molar mass of potassium hydrogen phthalate (KHP) is approximately 204.22 g/mol.
How many Moles of NaOH equals the moles of KHP?
When titrating NaOH with KHP (potassium hydrogen phthalate), the number of moles of NaOH will be equal to the number of moles of KHP at the equivalence point. This is because the reaction is stoichiometric, with one mole of NaOH reacting with one mole of KHP.
How many grams of KHP will be required to titrate 50 mL of 12 M NaOh solution?
To determine the grams of KHP required, you first need to calculate the number of moles of NaOH present in the 50 mL solution. Then, using the balanced chemical equation of the titration between NaOH and KHP, you can find the mole ratio. From the mole ratio and the moles of NaOH, you can calculate the moles of KHP needed and then convert that to grams of KHP.
Why is KHP used as a primary standard for non aqueous titration?
Potassium hydrogen phthalate (KHP) is used as a primary standard for non-aqueous titrations because it is a highly pure compound that can be easily dried to a constant weight. It also has a high molecular weight, which leads to more accurate measurements during the titration process. Additionally, KHP has a stable structure that makes it less prone to decomposition compared to other compounds.
What is the correct abbreviation for potassium hydrogen pthalate?
KHP
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.
