What is the molar ratio for this reaction for KHP NaOH?
Explanation: Your goal here is to standardize a solution of sodium hydroxide, NaOH , by using potassium hydrogen phthalate, KHP . The important thing to notice here is that you have a 1:1 mole ratio between the two reactants.
How many moles of NaOH will react with the KHP dissolved in water?
What is the molarity of the NaOH solution? 1 mole of KHP reacts with 1 mole of NaOH.
What is the molarity of KHP?
KHP (MWT = 204.22 g/mol) is a monobasic acid that contains one mole of neutralizable hydrogen per mole of compound.
How many moles of NaOH will react with 1 mole of potassium hydrogen phthalate?
one mole
A commonly used primary standard for titration with sodium hydroxide solution is the weak acid potassium hydrogen phthalate or KHP (C8H5O4K). In this reaction as well, one mole of KHP completely reacts with one mole of NaOH.
How do you make potassium hydrogen phthalate?
The present Potassium Hydrogen Phthalate that generally uses of institute, its preparation method is: add 6kg deionized water and 6kg phthalic anhydride in reactor, heating for dissolving takes 3~4 hours, adds water 6kg with stainless steel cask simultaneously and dissolves 5kg potassium hydroxide.
How many moles of NaOH are required to react with this number of moles of KHP?
From the weight of KHP used, we calculate the moles of KHP. Exactly the same number of moles of base is needed to neutralize this number of moles of KHP since based on the balanced equation, one mole of NaOH reacts with one mole of KHP.
What is the molarity of NaOH?
1 Expert Answer The molarity of NaOH is 2.002 x 10 -2 moles x 1000 mL/L / 25.0 mL = 0.801 Molar.
How do you convert moles of KHP to moles of NaOH?
The number of moles of KHP is found by dividing the mass of KHP by the molecular weight of KHP. 2. The number of moles of NaOH is found by multiplying the moles of KHP by the mole ratio of NaOH to KHP given by the above, balanced chemical reaction.
What is the molar mass of potassium hydrogen phthalate KHC8H4O4?
204.22 g/molPotassium hydrogen phthalate / Molar mass
How do you find the molar concentration of NaOH?
Formula of Molar Concentration
- The molar concentration formula is given by,
- HCl + NaOH → NaCl + H2O.
- n(HCl) = (35.0 / 1000 dm3) × 0.250 mol dm-3
- The mole ratio NaOH : HCl = 1:1.
- Now we have the equation,
- 25 cm3 = 25 / 1000 dm3
- Therefore, the molar concentration of NaOH.
- Molar concentration of NaOH = 0.350 mol dm-3
What is the reaction between KHP and NaOH?
The reaction between KHP and NaOH is shown by the balanced equation KHC8H4O4 + NaOH = NaKC8H4O4 + H2O. KHP stands for potassium hydrogen phthalate, which has the chemical formula KHC8H4O4. When KHP and NaOH combine, a positive hydrogen ion leaves the KHC8H4O4 and a negative hydrogen atom leaves the NaOH.
What happens when sodium hydroxide reacts with potassium hydrogen phthalate?
Now onto the word equation. Potassium hydrogen phthalate reacts with sodium hydroxide. This means that realistically the sodium must react to make something with either the potassium, the hydrogen or the phthalate.
Why is sodium potassium phthalate an acid and not a base?
One of the most important is that an acid will react with a base to form something plus water. Sodium hydroxide is the most common base. A hydroxide is desperate for a hydrogen so it can form water. Then all you are left with is sodium potassium phthalate.
What is potassium hydrogen phthalate?
Potassium hydrogen phthalate, KHC 8H 4O 4(abbreviated KHP), is a non-hygroscopic, crystalline, solid that behaves as a monoprotic acid. It is water soluble and available in high purity. Because of its high purity, you can determine the number of moles of KHP directly from its mass and it is referred to as a primary standard.
