If you made up a solution of naoh by adding 0.010 mole of solid naoh to 1.0 liter of distilled water, what would be the concentration of the oh-(aq)?

One of the cell membrane's functions is to protect the cell keep wastes in the cell create new cells keep light out of the cell

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
