A chemist needs to create a series of standard Cu²⁺(aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 10.00 mL of a 2.86 M Cu²⁺(aq) stock solution to a 250.0 mL volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 25.00 mL of the second solution to a 50.00 mL volumetric flask, and he adds enough water to dilute to the mark. Calculate the concentration of the Cu²⁺(aq) solution in the 50.00 mL volumetric flask.Concentration: [ ] M

In titrations, a standard solution is used; this is called a stock solution. It is diluted by adding…

Phenobarbital was introduced in 1912 for the treatment of epilepsy. It is an anti-convulsant and sedative-hypnotic drug and used to control seizures. The measurement of phenobarbital is by fluorescence method. A 5.00 mL aliquots of an unknown containing phenobarbital were delivered to 50.00 mL volumetric flasks. The following volumes of a standard solution of phenobarbital, 2.00ug/mL, were then introduced to the volumetric flasks before diluting to volume with the corresponding signals on a fluorometer equipment. Find the concentration of phenobarbital in the original unknown sample.
A sample with a mass of 1.340 g was dissolved in water, releasing chlorine ions. The aqueous solution was treated with access AgNO3(aq), the AgCl precipitate collected and weighted. Its mass was 2.709 g. What percentage by mass was the original sample? Make sure to use the correct number of significant figures in your answer.
O Chemical Reactions Standardizing a base solution by titration 3/5 Bis A chemistry student needs to standardize a fresh solution of sodium hydroxide. He carefully weighs out 36. mg of oxalic acid (H2C2O4), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250. mL of distilled water. The student then titrates the oxalic acid solution with his sodium hydroxide solution. When the titration reaches the equivalence point, the student finds he has used 35.1 mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Round your answer to 2 significant digits. Ом OP G
Sodium hydroxide solution was standardized against one gram of potassium 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. (a) What is the standardized concentration of the solution? (b) If the task is to prepare a one tenth of a molar solution, what is the percent accuracy of the preparation? 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. (c) What is 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: (d) Milk (MW, lactic acid =90) (e) Juice (MW, citric acid = 192.4; one mole citric acid reacts with three moles NaOH) (f) Vinegar (MW, acetic acid = 60) If you are a food safety inspector, would the sample pass if (include reason) (g)…

A sample of 7.89 g of Mg(OH)2 is added to 24.6 mL of 0.190 M HNO3. How many moles of Mg(NO3)2 are present after the reaction is complete? Express your answer in moles to three significant figures.
The reaction of NaOH and HCl produces aqueous NaCl as a product. You are assuming that the small amount of aqueous salt does not influence the final measurement. But it's still important to quantify the amount as evidence so that you can support that this assumption is reasonable. If you mix 58.4 mL of 1.000 M NaOH with 58.4 mL of 1.000 M HCl, what is the concentration of NaCl(aq) in the resulting solution?
