Chem 2 exam 3

inert ions

strong acids and strong bases

They don’t make H3O or OH-

don’t change the Ph

why do higher charges make an ion more acidic?

The higher charge makes the ion more able to hydrolyze water by pulling out hydroxide

How do two solutions qualify as a buffer

need a weak acid or a weak base (establishes equilibrium)

Need an ion in common with WA or WB (manipulates equillibrium)

what does a common ion do to a non-reversable reaction

NOTHINGGGGGUH

= no equilibrium

Ionization reaction is not controllable

explain common ion effect for buffers

The salt, having an ion in common with the weak acid or weak base, provides a means of shifting that equilibrium in reverse, which lessens the concentration of hydronium or hydroxide produced

what pH does a neutral solution have?

7.00

buffer pH solutions

Need to solve for hydronium or hydroxide. u don’t do x squared
