A) given 37ul of a 100 mg/ml stock solution of bovine serum albumin (bsa), diagram the most accurate procedure so you end up with at least 500ul each of 5ug/ul, 0.5 ug/ul, and 0.05 ug/ul working solutions of bsa. b) using the bsa working solutions created above, how much and which concentration would you pipet into three different centrifuge tubes so you end up with 20 ug, 2 ug, and 0.2 ug of bsa? (note: remember to stay within the accurate range of your pipetman.)

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
