Transcript of Introduction To Acids & Bases
Hydrogen-containing molecular compound whose molecules yield H+ ions when dissolved in waterWhen dissolved in water, they have a sour
tasteAcid comes from the Latin acidus which
means sourpH>7corrosive
Acetic acid gives vinegar it’s sour taste Ascorbic acid (Vitamin C) common ingredient in
food for sour taste
Strong acids transfer almost 100% of their hydrogens to water
H2SO4 (sulfuric acid)= H+(hydrogen) and SO4-
(sulfate ions) HCl (hydrochloric acid)=H+(hydrogen) and Cl-
(chloride ions)
Weak acids transfer less than 5% of their hydrogens to water
HC2H3O2=(acetic acid) H2CO3=(carbonic acid)
Hydrogen-containing molecular compound whose molecules yield OH- ions when dissolved in waterWhen dissolved in water, they have a bitter
tasteBase solutions feel slippery or soapy to the
touch. CorrosivepH>7
Sodium hydroxide is also known as lye and is very caustic to the touch
Strong acids transfer almost 100% of their hydroxyls to water
NaOH (sodium hydroxide)Na + + OH-
LiOH (lithium hydroxide) Li + + OH-
Weak bases transfer less than 5% of their hydroxyls to water
Only one is fairly common NH3 (aqueous ammonia)NH4
+ +OH-
