Answer:D

Please solve this step by step. Let me know if I am suppose to memorize anything. Why can the others be the right answer? Provide an example of each please.

If someone could help me solve the first column of trial #1, I just need to see the steps to solve and then I can finish the rest. Thank you!

The solubility of Borax equal to the number of moles of The number of moles of Borate ions produced in solution is the solubility of solid Borax that dissolved, therefore the concentration of Borate ions is equal to Borax in water. that of borateton Note that the sodium theoquilibrium solution calculate the concentration. By finding the borate ion concentration experimentally you can casily Reaction 2. corresponding sodium ion concentration, and therefore the equilibrium constant for PROCEDURE PREPARATION OF BORAX-BORATE EQUILIBRIUM MIXTURES 1. Room Temperature Solution: Add 3 grams of solid borax, 50 mLofdistilled water and a stir bar to a 100-mL beaker Place on a magnetic stirrer and stir the mixture for at least 15 If minutes. Periodically stop the stirring and make sure there is undissolved borax present. not add some more borax There must be undissolv boraxpresent in order to have 2. equilibrium. Why? a stir Ice Bath Temperature solution: Add 3 grams of solid borax 50 mL of distilled water and a second 100-mL Place this beaker in an ice-water bath and place the bath on magnetic stir for 25-30 minutes. As above, check to make sure there is undissolved stirrer and borax present and add more if necessary. Borate on is weak base o can be titrated with a sandardized hydrochloric acid solution according to Reaction 3 (3) or more simply (4) Note that it requires 2 moles of hydrochloric acid per mole of borate ion for the titration. 3. The HCI solution has been prepared for you by the stockroom. It should be approximately 0.2 M, however, on your data sheet you will need to record the exact molarity of the HCI solution as given on the bottle. 4. Prepare the Buret: Pour approximately 70 to 80 mL of the standard (0.2 M) HCI solu tion into a 250 ml beaker. Record its molarity on your repolt sheet. Clean a 50-mL buret, rinse it with 5-10 mL of HCI solution and let drain. Close the stopcock and fill the buret with the HCI solution.
