4 years ago. reading after titration 42.37 mL. KHP is an abbreviation for KHC8H4O4, potassium hydrogen phthalate. the NaOH solution: mass of KHP 2.354 g; buret reading before titration 0.33 mL; buret. A solution of sodium hydroxide is standard-ized against potassium hydrogen phthalate (KHP, formula weight 204.2 g/mol). KHC8H4O4 + NaOH -----> KNaC8H4O4 + H2O. From . Info: NAOH might be an improperly capitalized: NaOH Info: NAKP might be an improperly capitalized: NaKP Instructions and examples below may help to solve this problem You can always ask for help in the forum Instructions on balancing chemical equations: Enter an equation of a chemical reaction and click 'Balance'. the following data, calculate the molarity of. This is called an acid salt because it has a metal ion, which makes it a salt, and hydrogen, which makes it acidic. Anonymous. 1.54g of KHP is equivalent to 0.00754 mol of KHP. Lv 4. … 0 1. Source(s): https://shrink.im/a8065. KHC8H4O4(aq) + NaOH(aq) --> KNaC8H4O4(aq) + H2O(l). This is an acid and base reaction. The NaOH is dissolved by filling the volumetric flask to the mark. Answer in units of M. I assume NaOH is in the burette. The molar mass of KHP is approximately 204.22 g/mol. 5 years ago. KHP a weak acid reacts with a strong base sodium hydroxide to produce a weak base KNaP plus water.The reaction proceeds according to the equation: KHC8H4O4(aq) + NaOH(aq) --> KNaC8H4O4(aq) + H2O(l) Source(s): I did a lab like this last semester. 5 5. akhras . To perform each titration approximately 2.5 g of KHP is transferred into a … Khp Naoh. This is an acid-base reaction, which produces a salt and water. Aim To standardize a sodium hydroxide (NaOH) solution against a primary standard acid [Potassium Hydrogen Phthalate (KHP)] using phenolphthalein as indicator. The titration reaction of KHP with NaOH is as follows: $\ce{C8H5KO4 (aq) + NaOH (aq) → H2O + C8H4NaKO4 (aq)}\nonumber$ The NaOH solution is prepared by measuring out about 25 g of NaOH(s), which is then transferred to a 1 L volumetric flask. It acts like a monoprotic acid.
