what will the molar analytical concentration of Na2CO3 in the solution produced when 25 ml of 0.2 M of AgNO3 is mixed with 50 ml of 0.08 M Na2CO3?
2. A chemistry student is doing a titration lab in D314 and needs to make up 2 liters of NaOH for the class and standardize the NaOH with the organic acid KHP (MW 204.2 g/mol). The instructions say 5 grams/ liter of NaOH pellets which is - 0.1 M by the molar mass of NaOH. The student weighs out 10 grams of NaOH and dissolves it in 2 liters of water. The student then weighs out 0.4120 g of KHP and puts the organic acid in 50 mL of water and adds ~ 3 drops of 1% phenolphthalein indicator. To reach the endpoint (pink) where moles KHP are used up with NaOH, he adds 17.5 mL of the NaOH from the buret. What is the concentration of the NaOH? If he repeats this 2 more times an adds 16.9 mL and 18.2 mL what is the average concentration of the NaOH and the % difference? K
