How to figure out whether a giving compound is an acid or Base without looking at the arrows of the reaction.?

Also, how we know whether it's strong or weak acid or base? Please solve the follwoing and explain if you don't mind:





LiOH , KBr, BaSO4How to figure out whether a giving compound is an acid or Base without looking at the arrows of the reaction.?
I think all acids have an H at the beginning and all bases end in a OH, but I forget which are strong and which are weak.How to figure out whether a giving compound is an acid or Base without looking at the arrows of the reaction.?
Look at a Periodic Table as you read this.


Learn off some strong bases e.g. LiOH, NaOH, KOH.


Some strong acids: HCl, HBr, HF, but also H2SO4 and HNO3.


Weak bases include many carbonates and bicarbonates.


Weak acids include very many organic acids e.g. carboxylic acids such as acetic acid (i.e. Ethanoic Acid)





KBr, BaSO4 are neutral
