- Why did you use KHP to standardize the NaOH solution?
The reasons KHP is used as a primary standard are as follows: (1) It is not hydroscopic, (2) it has a high molecular weight, so a reasonable amount to titrate can be easily weighed, and (3) it is
- Why is KHP used as a primary standard? - Answers
KHP a is good primary standard for several reasons It's rather cheap, the purity level is high, it's water soluble, and best of all, it's chemically stable
- How many grams of K HP are needed to neutralize 18. 64 ml of a . . . - Answers
Molarity = mols of solute L of solution 1004 = mols of NaOH 01864 moles of NaOH = 00187 Moles of NaOH = Moles of KHP Now, multiply 00187 by the molar mass of KHP 00187*204 22 = 38 g KHP
- How many Moles of NaOH equals the moles of KHP? - Answers
How many moles NaOH would be in 450 mL of 0 25 N NaOH? First, calculate the number of moles of NaOH: Moles = Molarity x Volume (L) Convert mL to L: 450 mL = 0 45 L Moles = 0 25 N x 0 45 L = 0 1125
- What is the shortened structural formula for KHP? - Answers
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
- Why is KHP used as a primary standard for non aqueous titration . . .
KHP (potassium hydrogen phthalate) is available extremely pure (which is always good for a primary standard) and gives a very sharp end-point especially with Crystal Violet Indicator
- Why is perchloric acid standardized using potassium hydrogen . . . - Answers
Perchloric acid is a strong acid, whereas potassium hydrogen phthalate (KHP) is a weak acid Therefore, perchloric acid will protonate KHP to form phthalic acid In other words, even though both
- What is the structural formula for potassium hydrogen phthalate?
Potassium Hyrdogen Phthalate can be written as KHP The balanced equation for Potassium hydrogen phthalate and calcium hydroxide is:2KHC8H4O41- (aq) + Ca(OH)2 (aq) -----> Ca2+ (aq) + 2KC8H4O41- (aq
