Part B

Why use tweezers to put disks on the plate?
Why sterilize tweezers after each disk is put on the agar?
Why spread the bacteria out all over the agar plate?
Why put a disk with NO antibiotic on each agar plate?
Why put a disk with newly purchased, fresh antibiotic on each plate?
Why put so many disks on each plate?
Why wait 16-20 hours after you have put the bacteria and antibiotic disks on the plate?

Part B What is the pH after 0.150 mol of HCl is added to the buffer from Part A? Assume no volume change on the addition of the acid. Express the pH numerically to three decimal places. Part A What is the pH of a buffer prepared by adding 0.809 mol of the weak acid HA to 0.507 mol of NaA in 2.00 L of solution? The dissociation constant K a of HA is 5.66× 10 −7 . Express the...

For each of the following you should decide a) What test would you use? b) Why would you use this test? You wonder if changing the format on a statistics test will change the average mark on the test. You randomly select half the class and give them the standard test. The other half receives the test with the new format. You then compare the marks for each half. In analyzing the data you notice that the group that got...
