Click on the “2”
to progress to
the question.
The final
category is:
Explain the
difference..
Explain how the
concentration of an acid
is different from its
strength.
An acid’s strength is the same
no matter what the
concentration. For example 1
M HCl and 3 M HCl are both
the same strength (same
amount of H+ ions produced),
but one 1M is more dilute than
3M It’s concentration
changes with the amount of
water added to the substance.
