Chemistry Unit 13-Acid and Bases

do acids donate or receive and what is connected to them

Acids donate an h+ proton and connected to conjugate base

do bases donate or receive and what are they connected to?

bases receive an h+ proton and are connected to conjugate acid

what is NH4+

acid

what is NH3

base

amphoteric substance

substance that either donates or accepts hydrogen ion

what are basic/acidic properties of aqueous solutions when it involves the solvents water dependent upon?

equilibrium

if H+ >1.0×10-7 solution is(pH<7)

acidic

if H+ <1.0×10-7 solution is (pH>7)

basic or alkaline

if H+=1.0×10-7 solution is (pH=7)

neutral

how do acids taste

sour

what do bases taste like(soap)

bitter

how do bases feel

slippery

strong acids

HNO3, H2SO4,HCL,HCLO4,HBR,HI

strong acids _____ ionize in solution (reversible reaction?)

completely, no

strong base____ ionize in solution

completely

weak acids____ ionize(reversible?)

partially(less than 1%), yes

weak bases ____ ionize(reversible?)

partially, yes

weak acids Ka: as Ka decreases…

less H+ is formed in solution, so acid is weaker

weak bases Kb:as Kb decreases, less OH- is formed so base is weaker

what do base indicators do

they produce a color change in an acid base reaction
