Can you identify Strong/weak acids and strong/weak bases? Here is a shortcut for you to use whenever you are in an "identifying strong/weak acid-base" type situation.
Strong acids:

and

Two others that you should remember as strong are:

and

Apart from these, every other acid that you may encounter in your course will be a weak acid! You've just hit two targets with one arrow!
Strong Bases:
Again to figure out which one's a strong base, you don't have to remember them all.
If you see any hydroxide with the following cation attached to it, it's a strong base!
Yes! These are your familiar metals-Alkali and Alkaline Earth metals.

Acids are naturally found in many food stuff. But recalling the names of the acids in different food items isn't easy every time. So, what do we do?
You can think of other things related to the food such as, what is the food item mostly known for, or where is its name derived from.
For example,we know that lemons are a rich source of Vitamin-C. Link the letter C to Citric acid. With that, you can relate Citric acid to Lemons.
