The indicator used in the testing acids to neutralization lab
which turned purple when neutral was
called…
We add this to a product (as we did in our last lab) when we want to measure the acidity/ basicity of a
substance.
Make a statement about the relationship
of HCl (pH 0) and vinegar (pH3).
Make sure you include a phrase stating “is
___times more _______”
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.
