What produces H+ in a solution
What is an Acid
What type of solution has [OH-]> 10-7 and [OH-]> [H+].
What is Alkaline Solutions
Fill in the blank:
H+ OH- Type of solution
1.0x 10 -3 ? ?
H+ OH- Type of solution
1.0x 10 -3 1.0x 10 -11 acidic
This particular case could not be an Arrhenius base.
What is NH3 ammonia
What is a base
What is a proton acceptor?
What is a base
When an acid loses a When an acid loses a hydrogen ion it becomes a...hydrogen ion it becomes a...
Conjugate base
Fill in the blank:Fill in the blank:
Some substances, such as water, are amphoteric, what is another
name for amphoteric?
What is amphiprotic
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 the end point
What type of indicator is this...
What is phenolphthalein
A solution is tested: methyl red= yellow and
bromothymol blue = yellow. What is the concentration of the
sample?
What is six
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
