1. Given the initial stock concentration 0.1M NaOH. An unknown acid solution was diluted 1:5 times to a final volume of 20 mL. The acid was titrated with stock NaOH with phenolphthalein color indicator. When 35 mL of NaOH was titrated the solution turned purple. Calculate the concentration of the acid in the original solution. Remember after you titrate the 35 mL the final volume is larger so you have to back calculate using dilution equations. I want 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) 0.5100 Volume of NaOH required to neutralize...
