What is going on in the hexane layer at the end of a Group I Anion experiment? On a qualitative Analysis for Anions experiment, to a sample, I had to add 3 M HNO3 until it was just acidic. Then, I had to add 3 drops of NaOCl solution then 1mL hexane. After shaking it well, if the solution was yellow, the anion was Br-. If the solution was brown or purple, it was a I- Anion. What is going on with the hexane layer? What does it have to do with the periodic table?

3. how would the following errors affect the concentration of Cl- obtained in question 2b? give your reasoning in each case. a. the student read the molarity of AgNo3 as 0.02104M instead of 0.02014M b. the student was past the endpoint of titration when he took the final buret reading.
Conducting a titration Your objective is to determine the concentration of a solution of acid HA by means of an acid-base titration, using a 0.15 M solution of the base B(OH)2 and methyl orange as indicator. The unbalanced reaction between HA and B(OH)2 is shown below. Figure 3 shows the experimental set-up: the analyte was 20 mL of 0.15 M B(OH)2, and the titrant was the solution of HA of unknown concentration. B(OH)2 + HA → BA2 + H2O Materials provided a solution of HA of unknown molarity (titrant) a solution of B(OH)2 of concentration 0.15 M (analyte) methyl orange indicator Equipment per station Stand, clamp, white tile conical flask (100 mL) Burette (50 mL) Pipette (25 mL) Glass funnel Paper towels, pasteur pipettes, pen (for labelling glassware), beaker a) Using Figure 3 and the equipment and materials lists provided, outline how you would carry out a series of titrations to determine the molarity of the HA solution (Wordcount: 250 words). b) The starting and end…

In a titration of HNO₃, you add a few drops of phenol-phthalein indicator to 50.00 mL of acid in a flask. You quickly add 20.00 mL of 0.0502 M NaOH but overshoot the end point,and the solution turns deep pink. Instead of starting over, youadd 30.00 mL of the acid, and the solution turns colorless. Then,it takes 3.22 mL of the NaOH to reach the end point. (a) What isthe concentration of the HNO₃ solution? (b) How many moles of NaOH were in excess after the first addition?
15.00 mL of an unknown concentrated solution was diluted to 100.0 mL. Then 35.00 mL of this diluted acid solution was titrated ith 23.24 mL of 0.3724 M standard NaOH solution to reach the ending point. What is the molarity of the original concentrated acid solution?
You are asked to weigh 2 g of lithium and add it to 1500 ml of distilled water +2 drops of indicator, knowing that the density of water is 1 at room temperature while conducting this experiment. After determining the molarity of the LIOH, you need to know how many volume should be taken to reach the final concentration. Therefore, use the one underneath, so the molarity after dilution will be 0.025 M instead of 0.25 MAfter knowing the amount of LiOH, you need to dilute to prepare 0.025 M of LiOH in a 3000 ml solution. Show your calculation and units. dont forget to use Use this equation to calculate ( CLiOH x VLiOH) before dilution = (CLiOH x VLiOH) after dilution
