what does the pH scale actually represent?
The amount of [H+] in a solution.
Red litmus turns ____ in a basic substance
blue
If a substance has equal parts [H+] and [OH-], then we would call it neutral.
What are the products of a neutralization reaction?
Salt and Water
name one common acid
Answers Vary
Which of these are bases?
A) HCN B) HClO4
C) RbOH D) H2SO4
C) RbOH
Name a chemical compound for each..
-a pH of 0
-a pOH of 0
-a neutral pH
-HCl
-NaOH
-Water
If a solution has a pOH of 8, what color will it be with a Phenolphthalein indicator?
Colorless.
Finish this reaction.
HBr + NaOH -->
H2O + NaBr
Acids will react with metals, true or false
True
[OH-] concentration can be calculated from both the [H+] or from pOH.
If [H+] = 1.0x10-9, what is the [OH-]?
[OH-] = 1.0x10-5
AS [OH-] increase, the pH of the solution(increases/decreases)?
Decreases, towards 0.
Bromothymol blue will turn _______ in a solution with that has [H+] = 1.0x10-10
pH would be 10, so BLUE
100 mL of 1.0 M HNO3 and 100 mL of 2.0 M KOH are mixed together.
Is the result going to an acidic, basic, or neutral?
Basic, the KOH is more concentrated.
Which of these concentrations of Hydronium represent an acid?
A) 1.0x10-7 B) 1.0x10-3 C) 1.22x10-5
B) 1.0 x 10-3
Which solution is most basic? These are all [OH-]
A) 1.0x10-2
B) 1.0x10-12
C) 4.75x10-4
A) the pOH would be 2, so pH would be 12.
Calculate the pH (w/correct significant digits)
[H+]= 2.65 x 10-3.
pH is 2.58
It also turns slightly blue in bromothymol blue, what is the pH most likely to be?
pH is like neutral, 7.
How many liters of 2M NaOH are needed to exactly neutralize 1 L of 1M HCl?
0.5 Liters of NaOH would be needed.
If 1 mole of each of these substances were dissolved in 1 Liter of H2O, which solution would have the highest [H+]?
A) CH3COOH B)NaCl
C) KOH D)NH3
A) CH3COOH - Vinegar
Water can act as an acid or a base. Based on the reaction below, what would be your products?
HCl + H2O -->
H3O+ + Cl-
Find both the pOH and [OH-] is the pH of a substance is 9.8
[OH-] = 6.3x10-5
pOH = 4.2
What is the [H+] of a solution that turns blue in bromothymol blue but stays colorless in phenolphthalein?
Answers must fall into my answer's "range"
2.5x10-8 --- 1.0x10-8
An unknown acid needs to be neutralized in order to be disposed. When titrating, a lab worker found that 15mL of 5.0 NaOH neutralized 100 mL of the acid.
What is the concentration of this acid?
[H+] = 0.75
