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...

As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...

1. Calculate how many milliliters (mL) of 2 M NaOH will be needed to make 0.50 L of a 0.2 M aqueous NaOH solution. 2. You will use a weighted amount of KHP (a weak acid) to standardize your ~ 0.2 M NaOH solution. Assuming that you made exactly 0.2 M NaOH, calculate how many grams of KHP will react with exactly 15 mL of 0.2 M NaOH. Use the information below to help answer this question: _C02 K+ CO2...
