Acids/Bases/ch 15. Acid/base. Electrolyte—any substance which will form ions in solution and conduct electricity Three classes of electrolytes: A) Acids B) Bases C) Salts. Acid/Base. Properties of Acids: A) taste sour B) turn litmus red C) clear in phenolphthalein
Polyprotic acids---those with more than one “H” to ionize
Al(OH)3(aq) Al+3(aq) + 3OH-(aq)
H2SO4 + H2O => H3O+ + HSO4-
acid base c. acid c. base
Calculate the pH of the following:
a) [H+] = 3.0 X 10-8
b) [OH-] = 4.0 X 10-6
c) [H3O+] = 8.2 X 10-6
Determine for each example if it is acid, base, or neutral.
What is the molarity of a NaOH solution if 40.0 ml of the solution is neutralized by 35.6 ml of .24 M solution of HBr.
VaMa = VbMb
35.6 ml x .24 M = 40.0ml X Mb
Mb = .21 M
ex: sulfuric acid reacts with calcium hydroxide.
