Like all equilibrium constants, kw varies somewhat with temperature. given that kw is 3.31 × 10−13 at some temperature, compute the ph of a neutral aqueous solution at that temperature.

i'm assuming that the correct answer is indeed the first one/ "a"..

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
