What is the difference between a strong acid and a concentrated acid? |
Strong acid: -H+ ions break from their compounds very easily in solution. Concentrated Acid; Lots of acid in the solution |
|

What is the difference between a strong acid and a concentrated acid? |
Strong acid: -H+ ions break from their compounds very easily in solution. Concentrated Acid; Lots of acid in the solution |
|
|
|
What is the difference between a weak acid and a dilute acid? |
Weak acid: -H+ ions do not break from their compounds easily in solution (stay mostly bonded) Dilute Acid: Not much acid in the solution |
|

What does the PH scale decipher? |
The amount of hydrogen the compound could release, deciphers how acidic or basic a substance is |
