You should know if acids are strong or weak. One option is to memorize the strong ones, but in general you can find trends to make it easier to determine how strong an acid is.

Some of the trends we see to tell the differences is stronger acids have lower pKa values, strong acids lose H+ easily and the resultant anion must be stable. With weaker (larger) bonds it is easier to remove the H+. Short bonds are stronger where we can see the smaller elements trend towards the upper right of the periodic table. Short, stronger bonds are less acidic.

Yes you should memorize the strong acids so if you are asked to determine if an acid is strong or weak, you will know the answer based on if it's an acid you have memorized.
