Color indicators are organic
compounds that establish equilibrium
between their ________ form and
ionic form in solution.
What is molecular
The pH at which the color change
occurs is called the

What is phenolphthalein
A solution is tested:
methyl red= yellow and
bromothymol blue = yellow.
What is the concentration of the

HCl is a strong acid. In an aqueous
solution it will ionize
%
What is 100
H2SO4(aq) + HOH(l)  H3O+(aq) +HSO4-(aq)
How many ionisable hydrogen(s)
does this equation contain
What is two
Find the percent ionization of
0.100M solution of formic acid if
it’s [H +] = 4.22x10-3 M
What is 4.22x10-3 x 100 = 4.22%
0.1
A 0.40 M solution of HClO3 is 0.027%
ionized. Find the Ka for this acid.
[H+] = 0.027 • (0.40) = 1.08 x 10-4 M
100
HClO3(aq)  H+(aq) + ClO3-(aq)
Ka = [H+][ClO3-]
[HClO3]
Ka = (1.08 x 10-4)(1.08 x 10-4)
(0.3999)
Ka = 2.9 x 10-8
Acids taste sour, bases taste

What is salt
+ water
Calculate the volume of seawater
with a pH of 7.80 that contains 1.0
mol of hydroxide ions.
pH = 7.8
= pOH = 6.2
= [OH-] = 6.3 x 10-7 M
6.3 x 10-7 mol = 1 L
1 mol = ?L
= 1.58 x 106 L
A
is a technique for finding
an unknown concentration of one
chemical from the known
concentration of a second chemical.
What is titration
Find the concentration of an HF
solution if 15.0 mL of 0.200 M KOH
just neutralized 20.0 mL of HF.
HF + KOH → KF + H2O
Step 1
Step 2
Step 3
n = MV = (0.200 mol / L)(0.0150 L) = 0.00300 mol KOH
x mol HF = 0.00300 mol KOH x
1mol HF = 0.00300 mol HF
1 mol KOH
M = n = (0.00300 mol) = 0.150 mol = 0.150 M
V (0.0200 L)

A titration shows that 242 mL of 0.500 M
NaOH will just neutralize all of the acetic
acid that is present in 150.0 mL of
vinegar. Find the % by mass of acetic acid
in vinegar.
NaOH + HC2H3O → NaC2H3O2 + H2O
Step 1 n = MV = (0.500 mol) (0.242 L) = 0.121 mol NaOH
L
Step 2 x mol HC2H3O2 = 0.121 mol NaOH x 1 mol HC2H3O2 = 0.121 mol HC2H3O2
1 mol NaOH
Step 3 x g HC2H3O2 = 0.121 mol HC2H3O2 x 60 g HC2H3O2 = 7.26 g HC2H3O2
1 mol HC2H3O2
Step 4 % mass = 7.26 g x 100 = 4.84% acid
150.0 g assumed
