A group of students titrate a calcium carbonate standard solution repeatedly in five experimental trials. Based on the five trials, the group detemines that the average concentration of the standard is 80.5 ppm with a standard deviation of 0.5 ppm. Using the equation for the Student's t confidence interval found in Appendix 1 of your lab manual and the t-value for a 95% confidence interval, calculate the confidence interval for which there is a 95% chance of finding the "true value" of the standard solution's concentration based on the data. Put your answer in the fomat # lower limit < "true value" < # upper limit. (Appendix 2 has an example that may be helpful.)

Analysis of a standard solution at a concentration of 5 ppm Fe (III) is done with a new analysis method. The experiment is repeated 3 times, and the average iron ion concentration is determined as 4.7 ppm. The standard deviation, s = 0.1, is calculated according to the results of the three experiments. Does the new analysis method contain systematic errors at a 95% confidence level? (Choose the t value from the Table) t values Degrees of freedom 95% CL 1 12.7 4.3 3.18 4 2.78 O a. A systematic error exists O b. Only random error exists
Q6. The following set of millimolarities were obtained when standardizing a solution: 10.67, 10.71, 10.66, and 10.45. One value appears suspect. Using Q test determine if it can be ascribed to accidental error, at the 90% confidence level.

You are analyzing the effluent from a lotion plant for parabens using HPLC. You have a working standard solution with a concentration of 59.4 ppm which returned a Peak Height of 10,164 and Peak Area of 5,315. You take 44.4 L of the water sample and concentrate it to 0.3 L and analyze this solution. The Peak Height is 9,119 and the Peak Area is 6,320. What is the concentration of parabens in the effluent of the plant in mg/L to two decimal places.
Introductlon In Part (a) of this experiment you will prepare a primary standard. Potassium hydrogen phthalate (KHP) is a monoprotic acid with the formula KHC,H.O. In this experiment KHP is used as the primary standard. A standard solution is one whose solute concentration is accurately known. If a solute can be obtained in a very pure, stable, weighable form, a primary standard solution of it can be prepared directly. You will then use the standardized sodium hydroxide solution to determine the acetic acid content of a dilute unknown solution. Procedure (0) Preparation of a Primory Standard Potassium hydrogen phthalate (KHP) is a primary standard. Weigh accurately by difference, approximately 0.8 g of KHP in a clean, dry weighing bottle and transfer it into a 250 ml conical flask. Add 75 ml of distilled water. Swirl gently. Cover the flask and leave to dissolve, swirling periodicaly. Cautlon: KHP is not highly soluble and care must be taken to ensure it is all dissolved before you…

For lab 4, we combined baking soda with vinegar, according to the chemical equation NaHCO 3 + CH 3COOH ==== NaCH 3COO + CO 2 + H 2O Consider 3 experiments: (i) 2g baking soda + 5mL vinegar, (ii) 2g baking soda + 10mL vinegar and (iii) 2g baking soda + 20mL vinegar. The amount of CO 2 produced was highest for (iii) and lowest for (i). For these experiments, which of the following is true?

Calculate the concentration (Mdil) of potassium permanganate (KMnO4) when 600 mL (Vconc) of the potassium permanganate solution is added to 400 mL of water. Note: first add the potassium permanganate solution (choose dropper) in the absence of water, move the sensor over the solution, and determine the concentration of the solution prior to adding water (Mconc). Knowing these three pieces of data, you can now calculate (Mail), and enter this calculated number as your answer. You can also confirm your answer by adding 400 mL of water to your 600 mL of potassium permanganate solution and checking the concentration with the sensor (NOTE: the sensor concentration will likely be slightly off the calculated number since it's difficult to add exact volumes in the simulator). Please report your numerical answer only with three significant figures and NO units (eg., 1.23). Mdildil MconcVconc A R
