Acids and Bases Test Review

Chemistry

Destructive, corrosive, and reactive

Acids and bases can be...

Sour taste and burn skin

Select the characteristics of an acid.

Tastes bitter and feels slippery

Select the characteristics of a base 

the pH scale

The strength of an acid or base is measured using:

0-14

The pH scale ranges from ____ to ____

acidic

Numbers lower than 7 means the solution is

basic

Numbers higher than 7 means the solution is

Drain cleaner

__________________ is an example of a strong base.

False

True or False: Only strong acids are dangerous, strong bases are not dangerous

Acids and Bases

A neutralization reaction is the type of reaction where these react.

Water and salts

A neutralization reaction always produces these.

Acid

When a compound starts with H, then is it an acid or a base?

Base

When a compound ends with OH, then is it an acid or a base?

True

True or False: The compound H(OH) is the same as the compound H2O.

False

True or False: KCl is considered a base.

Hydronium (H+)

Scale used to measure the concentration of this ion in a solution.

more acidic

The lower the number, the greater the concentration of hydronium. This means the solution is more acidic or less a acidic?

less acidic

The higher the number, the lower the concentration of hydronium. This means the solution is more acidic or less acidic?

0 to 14

The pH scale range is from:

0 and 7

Acids have values between:

7 and 14

Bases have values between:

7

A completely neutralized solution has a pH of:

pH scale of 7

Pure water also has a pH of this just like a completely neutralized solution.

OH

As H+ decreases, this increases.

H+ = OH

The pH scale of 7 is considered neutral because………….

0-7
