4. Sodium hydroxide solution was standardized against one gram of potassium acid phthalate. First trial used 52.0 ml of the solution while the second trial used 52.4 of the solution to reach the end point. Determine: (a) the standardized concentration of the solution? (b) the percent accuracy if you are going to prepare a one tenth of a molar solution The standardized basic solution was then used in getting the total acidity of a food sample. Ten milliliter of the acidic sample consumed 10.3mL in the first trial then 10.0mL in the second trial to reach endpoint. Determine: (c) the normality of the acidic sample? Compute the total acidity of the food sample assuming that ten grams of sample was dissolved to 25ml of solution if the sample is: (e) Juice (MW, citric acid = 192.4; one mole citric acid reacts with three moles NaOH) If you are a food safety inspector, would the sample pass if (include reason) () The stomach can only withstand 0.39-1.1% citric acid?

A bottle of anhydrous copper(II) sulfate was accidentally left uncapped for an afternoon, allowing it to pick up water from the environment. To determine the degree to which the compound was hydrated, a sample was analyzed. The initial weight of the partially hydrated copper(II) sulfate was 9.782. After drying to constant weight, the weight was 7.232. How may waters of hydration are present?
