A subatomic particles with no charge is known as a(n) ______.
neutron
According to the Arrhenius definition, bases produce ____ ions when dissolved in water.
OH- ions (hydroxide)
acidic
If carbonite was an acid, what would it be called?
carbonic acid
If the concentration of H+ ions of a solution is 0.00345 M, then what would its pH be?
pH = -log([H+])
pH= -log(0.00345)
pH= 2.46
An atom with more or less electrons than normal will have a charge. This is known as a(n) _____.
ion
A hydrogen with no electrons is essentially a ______.
proton or H+ ion
A pH of 7 is known as _____. An example of a liquid with a pH of 7 is _____.
neutral; water
If phosphate was an acid, then what would it be called?
phosphoric acid
(I will also accept phosphic acid)
Lemon juice has a pH of 2.45. What would the concentration of H+ ions be in a solution of lemon juice?
[H+] = 10-pH
[H+] = 10-2.45
[H+] =0.00354M
or
[H+] =3.54x10-3M
If a gas is in a sealed, elastic container and then had its temperature increase, what will happen?

pH stands for "the power of _______"
hydrogen
If fluoride were an acid, what would it be called?
hydrofluoric acid
What does the "M" stand for when you see something like "the solution was 3.2M"?
Any of the following are acceptable:
- M stands for molars or the molarity.
- M means the concentration of...
- M is moles per liter.
Atoms that have the same number of PROTONS, but differ in their mass and number of neutrons are known as _______.
Example: carbon-12 and carbon-14
isotopes
What is an acid and what is a base according to the Bronsted-Lowry definitions of acids and bases?
Acids = proton (H+) donors
Bases = proton (H+) acceptors
A solution was measured for its concentration of H+ ions. After collecting the data, it was determined there was a VERY HIGH concentration of H+ ions. Would this solution have a very high pH value, a very low pH value, or a pH of 7?
A high concentration of H+ ions would make it very acidic. Acids have a low pH value.
If sulfate was an acid, then what would its name be? Also, what would its formula look as an acid, if sulfate is written as SO42-?
Sulfuric acid (I will accept sulfic acid)
H2SO4
If the concentration of H+ ions of a solution is 3.23x10-10 M, then what would its pH be? Would this solution be acidic, basic, or neutral?
pH= -log([H+])
pH= -log(3.23x10-9)
pH= 9.49
This solution is basic (or alkaline)
