Solve correctly please. a 0.25 mol sample of a weak acid with an unknown pka was combined with 10 ml of 3 m koh and the resulting solution was diluted to 1.500 L the measured ph of the solution was 3.85 what is the pka of weak acid Please include formulas used and write answer legibly please. Include all steps aswell. Thankyou. Answer is 4.73
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
