H2So4 is liquidso how much ml of H2So4 take for 1N solution?
Sulphuric Acid requires, I believe 27.2ml to make a 1N solution.
Suppose your laboratory instructor inadvertently gave you a sample of khp that was contaminated with nacl to standardize your naoh how would this affect the normality you calculated for your naoh sol?
Potassium acid phthalate is a common primary standard used to standardize bases. Obviously, it would depend upon how much NaCl was present, but the end result will be to reduce the amount of available H+ for the mass of KHP-NaCl mixture. That would cause you to understate the concentration of the base.
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 stable at temperatures over 100°C so that any water may be driven off by heating.
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.
What is the molarmass of KHP?
71.0800g/mole
Which other primary standard can be used to standardize sodium hydroxide other than KHP?
sodium hydroxide is a secondary standard because it absorb the moisture from the air and its concentration will change

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
What is the molarmass of KHP?
71.0800g/mole
What is KHP and structure?
Potassium Hydrogen Phthalate
What is the balanced chemical equation of NaOH and H3PO4?
KHC8H4O4(aq) + NaOH(aq) → KNaC8H4O4(aq) + H2O(l) NaOH(aq) + KHP(aq) => Na+ + KP- + H2O(l)
What is 1n in fraction form?
1/1n
What is the correct abbreviation for potassium hydrogen pthalate?
KHP
