Titration

300

In the flame test lab, the splint reigniting showed

the presence of….

Oxygen or O2

400

Antacids are bases taken by people for what

purpose?

ailment

500

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.
