A pair of students standardize a sodium hydroxide solution using KHP and obtain the following concentrations: 0.1028 M, 0.1031 M, 0.1200 M, 0.1030 M and 0.1026 M. The students suspect that 0.1200 M is an outlier. Is 0.1200 M an outlier?
Yes, it can be possible due to lot of error human error , every machine has it's own error . As all other readings except the 0.1200M are almost same . So , there exist a very good precision and also have good accuracy . So that 0.1200 M is an outlier.

1. A student is asked to standardize a solution of sodium hydroxide. He weighs out 0.960 g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid). It requires 18.1 mL of sodium hydroxide to reach the endpoint. A. What is the molarity of the sodium hydroxide solution? ___M This sodium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid. B. If 12.8 mL of the sodium hydroxide solution is required to neutralize 27.8 mL of...
Preparation of Sodium Hydroxide Titrant: Prepare 500 mL of a 0.1 M sodium hydroxide solution by dilution of a 1 M sodium hydroxide stock reagent or from solid NaOH. This dilution need only be performed to 5% accuracy, that is, using a graduated cylinder and an Erlenmeyer flask. Store the diluted solution in a polyethylene bottle. Standardize the diluted solution against dry, solid KHP (potassium hydrogen phthalate) using phenolphthalein as an indicator and label the bottle with the concentration of...

1. A solution of sodium hydroxide (NaOH) was standardized against potassium hydrogen phthalate (KHP). A known mass of KHP was titrated with the NaOH solution until a light pink color appeared using phenolpthalein indicator. Using the volume of NaOH required to neutralize KHP and the number of moles of KHP titrated, the concentration of the NaOH solution was calculated. Molecular formula of Potassium hydrogen phthalate: HKC8H404 Mass of KHP used for standardization (g) 0.5306 Volume of NaOH required to neutralize...

Please explain in detail You are going to standardize a 0.80% solution of sodium hydroxide solution for which the molarity is approx 0.20M. You will have dry succinic acid (H2C4H4O4) , a 250 mL volumetric flask, a 25.00mL pipet, a 50.00mL buret, a phenolphthalein indicator solution, and other standard lab equipment. For each titration you will withdraw a 25.00mL sample of the succinic acid solution with a volumetric pipet. Therefore you will deliver exactly one-tenth of your initial mass of...
