Calculating the pH at equivalence of a titration A chemist titrates 100.0 mL of a 0.8108 M butanoic acid (HC3(CH2)2HCO2) solution with 0,0520 M KOH solution at 25 C. Calculate the ph at equivalence. The pKa of butanoic acid is 4.82. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.

your answer is c) plasma

gas

explanation:

smoke is the matter of a gas

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
