How do you find the unknown acid in a titration?

Your unknown solid is an acid. You will dissolve it in water, add some phenolphthalein indicator and then titrate to the end point with your standard NaOH solution. The unknown acid is monoprotic; it has only one acidic hydrogen per molecule.

How do you calculate the molarity of an unknown acid in acid base titration experiment?

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)

How can you determine the strength of an unknown acid?

Based on the molar mass you will determine the identity of the unknown weak acid. In water strong acids produce hydronium ions and strong bases produce hydroxide ions. The reaction of a strong acid with a strong base is represented with the chemical reaction shown in Equation 1.

How do I determine the unknown concentration of a base used in a titration?

  4. Step 4: Determine the concentration of HCl.
  5. Answer.
  6. MacidVacid = MbaseVbase

How do you find the concentration of an unknown solution?

Most of the protocol, the given formula to calculate the concentration of unknown substance is = Test OD/Std OD * Std Concentration.

How do you identify the identity of an unknown acid?

Use a Meltemp apparatus to determine the approximate melting point of the solid acid. Evaluate the results for molar mass, pKa, and melting point to determine the probable identify of the unknown acid from a list of choices.

How do you find the pKa of an unknown acid titration?

Calculate the pKa with the formula pKa = -log(Ka). For example, pKa = -log(1.82 x 10^-4) = 3.74.
