What is phenolphthalein

A solution is tested: methyl red= yellow and

bromothymol blue = yellow. What is the concentration of the

sample?

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 100HClO3(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 bitter

An unknown acid has a H+ of 3.9x10-3, what is the OH-?

What is 2.6x10 -12

Find the pOH of a solution with a [H +] of 6.7x10-3

What is 11.8

Acid + Base + water

What is salt

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 knownconcentration 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 n = MV = (0.200 mol / L)(0.0150 L) = 0.00300 mol KOHStep 2 x mol HF = 0.00300 mol KOH x 1mol HF = 0.00300 mol HF

1 mol KOH Step 3 M = n = (0.00300 mol) = 0.150 mol = 0.150 M V (0.0200 L) 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

LStep 2 x mol HC2H3O2 = 0.121 mol NaOH x 1 mol HC2H3O2 = 0.121 mol HC2H3O2

1 mol NaOHStep 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
