Know what kind of acid or what kind of bsae it is. Here are some rules

Strong acids include HI, HBr, HCl. or when the O atoms exceeds the number of prontons like HNO3, HClo3 and H2SO4

Weak Acids are

HF, Ch3COOH, C6H5COOH,

AND WHEN O atoms equal protons on exceed by one. like HClo

Strong base is

M20 or MOH

MO or M(OH)2

Weak Bases

are NH3 or anything with that

H+ ions raise the acidity of the compound, while OH- makes it more basic.

A formula you can use is this (assuming temperature to be held constant at 25C), based on the molarity within the compound:

[H+][OH-]=10^-14

The brackets indicate molar concentration.

The pH is found as follows:

pH=-log[H+]

The lower the pH, the more acidic. The higher, the more basic.

__________________________________________________

Example:

At room temp (25C), a neutral solution has molar concentrations as follows:

[H+]=10^-7

[OH-]=10^-7

The product (of 10^-7 and 10^-7) is 10^-14. (Again, these molar concentrations will always equal 10^-14. This is good to know for when you know, for example, the H+ concentration but need to determine the OH- concentration.)

Furthermore, the -log(10^-7) = -(-7)=7 --that is, a pH of 7, which is neutral.

So, to determine which is stronger, you can check their H+ concentrations or their OH- concentrations. Using the info above you can actually determine where each substance falls on the pH scale.

You can boil purple cabbages and then take the liquid that is left over...it should be light clearish purple. Pour the acid into it. The pinker the liquid turns, the more acidic the acid is. So if you have two acids, and one batch of cabbage juice turns light pink and the other turns dark bright pink, then you know that the darker one was more acidic than the other. And for bases, the darker greenish blue it turns, the more basic it is.

Maybe go online and type the name of the acid/base you want to know about and find it there. Hope this Helps.
