Methanoic Acid (HCOOH) is used as a preservative and in decreasing the spread of bacteria. You are performing a lab to determine the K, of methanoic acid. The list of equipment and materials you will be using are as follows: Equipment : Burette Stand, Burette, Erlenmeyer flask , pH meter, Lab Coat, Safety Goggles, Gloves Materials: 0.2 M NaOH solution , 25-ml methanoic acid Solution, Methyl Orange indicator a) Based upon the equipment and materials listed above, and your knowledge of titrations, write out at step by step, numbered procedure to explain the technique in determining the initial concentration of the methanoic acid and the hydrogen ion concentration of the acid at equilibrium. You carry out your experimental design and observe the following results: pH of CHOOH 3.47 Volume of CHOOH (mL) 25-ml Concentration of NaOH (M) 0.2 M Volume of NaOH (aq) needed to titrate CHOOH (aq) to endpoint 18.50-ml b. Determine the initial concentration of methanoic acid before equilibrium. c. Write the neutralization reaction for methanoic acid reacting with sodium hydroxide. d. Write the dissociation equation for methanoic acid solution. e. Determine the acid dissociation constant (K) for methanoic acid. f. Does the K, value for methanoic acid indicate that it is a strong or weak acid? Explain your answer based upon concentrations
