CALCULATIONS: 1. Write the equation for the ionization of hydrochloric acid. HCL H = + Cl - 2. Indicate which unknown part “B” acid you had and determine the concentration of hydronium ion in your part “B” acid. We had unknown #3 and the hydronium concentration is equal to the solution’s concentration because HCl is a strong acid, it dissociates completely and the hydrogen is basically what conducts the electricity so the concentration of it will be equal to the whole solution, therefore it is .001M. 3. What is the concentration of the original acid in part “B”? Explain your answer. By comparing the colors from our data table, we concluded that the concentration of the original acid in part “B” is .001 M. 4. Write the equilibrium equation for the ionization of acetic acid. Keq= [H+][C
