Hence, we first standardize the base against an appropriate primary standard. Wiki User Answered . Even, how many mL of water that has been used, THE SAME number of moles of KHP is present in the "preared KH solution" no matter what is the final … Asked by Wiki User. Apparatus: Cleaned and calibrated pipettes Burettes Conical flasks. Titration standards must be stable and be capable of being measured for amount very accurately. Answer. These two atoms combine with the oxygen from the NaOH to form H2O, which is the chemical formula for water. Why did you use KHP to standardize the NaOH solution? It is NOT important or the amount of water that was used to dissolved the KHP does not account or does not have any part in the mathematical computation(s). Therefore, the mass of NaOH should be treated as an approximate value. KHP is the primary standard to be used in standardization of NaOH solution. Chemicals: Sodium hydroxide AR Grade Oxalic acid AR Grade Phenolpthalene indicator. Even, how many mL of water that has been used, THE SAME number of moles of KHP is present in the "preared KH solution" no matter what is the final … That's why you use NaOH. The reaction between the two solutions is typically done using a process called titration, so that the concentration and volume of each solution is known … Your mom! PROCEDURE. Standardization of a NaOH Solution with Potassium Hydrogen Phthalate (KHP) Objective You will determine the concentration (standardize) of an unknown solution of NaOH using the primary standard, potassium hydrogen phthalate. How many grams of K HP are needed to neutralize 18.64 ml of a 0.1004 M Na OH … Why did you use KHP to standardize the NaOH solution? When KHP and NaOH combine, a positive hydrogen ion leaves the KHC8H4O4 and a negative hydrogen atom leaves the NaOH. This means that NaOH will absorb water in the atmosphere, and as a result when you measure the mass of NaOH on a balance you are likely measuring NaOH plus some amount of water. A typical standard for bases is the weak acid potassium hydrogen phthalate, KHC 8H 4O 4, which is frequently abbreviated KHP. Hence, based on the above theory our aim is to prepare and standardize sodium hydroxide using oxalic acid. Titration of a standard acid, such as KHP, with the NaOH solution can be used to accurately determine the concentration of the NaOH solution. Top Answer. 4 5 6. It is NOT important or the amount of water that was used to dissolved the KHP does not account or does not have any part in the mathematical computation(s). Answer to: Why do you need to use KHP to standardize a solution of NaOH?
