strength

[Naana Boateng 1I]

How can you calculate which acid/base is the stronger acid/base?

[Connor Kelligrew 2D]

If it was two acids you could calculate the pH values and compare, whichever is lowest is a stronger acid.
If it was two bases you could calculate the pH values and compare, whichever is higher is a stronger base.
If it was an acid and a basic you could calculate the pH of the acid and the pOH of the base, and whichever is lower is the stronger in its respective quality.

[Eli Aminpour 2K]

There are a few ways to tell. Strong acids and bases have extremely high K values for the chemical reaction of their disassociation in water. There are patterns too related to these higher K values (meaning very little product was left behind). Metal hydroxides tend to be strong bases (metal +hydroxide)
