Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Some sulfuric acid is spilled on a lab bench. It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. The sodium bicarbonate reacts with sulfuric acid as follows: 2NaHCO3 (s) + H2SO4 (aq) --> Na2SO4 (aq) + 2H2O (l) + 2CO2 (g) Sodium bicarbonate is added until the fizzing due to the formation of CO2 (g) stops. If 27 mL of 6.0 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?

One of your friends who likes gardening is attempting to make a solution that will increase some trace nutrients while also making the soil less acidic.* The planned solution will have the following concentrations: 0.03 M NaOH 0.008 M CaCl2 8 x 10-12 M Fe(NO3)2 You're going to help your friend out by checking to see if anything will precipitate out of this solution. Your friend is particularly worried about Ca(OH)2 [Ksp = 6.5 x 10-6] and Fe(OH)2 [Ksp = 7.9x10-16]. Your friend thinks they have done the math correctly so that no precipitates will form, but they don't know anything about ionic strength corrections.(NOTE: Assume molality = molarity. There's probably not much of a difference.) a) Calculate the ionic strength of the solution. b) Calculate the activity of hydroxide ions, aOH- c) Calculate the activity of Ca2+ ions. d) Calculate the activity of Fe2+ ions.
