Stronger acids are those that-
hold on to their protons more strongly
lose their protons more easily
more completely inhibit polarity in water
exhibit hydrogen bonding
The conjugate pair for a strong base is—
Strong base
Weak Base
Strong Acid
Weak Acid
For two acids of equal concentration, the stronger acid has —
a higher concentration of hydroxide ions

What color does litmus paper turn when placed in an acidic solution?

In 1923, G.Lewis suggested a simplistic way of describing reactions that did not fit the Bronsted-Lowry definition of acid-base reactions. He suggested that an acid is any species lacking an octet and conversely a base as any species with an unshared pair of electrons.
According to his definitions, all of following can be classified as a base except -
CH3-
CH3+
NH3
H2O
Which of the following reactions is between an acid and a base to produce a salt?
Neutralization
Combustion
Half Reaction
Hydrolysis
When investigating the pH of a solution, what effect is most likely observed when solid ammonium chloride is added to a dilute aqueous solution of NH3?
the pH decreases
the pH becomes 7
the pH increases
the pH does not change
If a solution has a hydrogen ion concentration of 1x10-13 mol/L it is
an acid
a base
a salt solution
water
When HCl is added to pure water, which of the following will occur?
the [H+] will increase
the pH will decrease
the [OH-] will decrease
all of the above
The addition of NaOH to pure water will
Cause the pH to increase.
Cause the pH to decrease.
Cause the pH to decrease.
Produce a salt water solution with no pH.
A solution has a [H+] of 1x10-3 M. This solution is a(n)
acid
base
concentrated solution
neutral solution
