Acids and Basis: Salts

[briannam_1F]

How does one calculate the pH of a weak acid and its salt?

[Minh Ngo 4G]

That's the ICE table problem!

[Venus_Hagan 2L]

most of the time when you are dealing with weak acids and bases, you will be using an ICE table

[WesleyWu_1C]

You would have to use an ice table and find the concentration of H3O+ (sometimes you will have to used the quadratic equation to find it). Then you plug in the concentration of H3O+ to get the pH.

When using an ICE Table, can you ever have a starting value of products, or is it always 0?

[William Chan 1D]

You can use an ICE table to help you figure out the concentrations in terms of known concentrations and changes in concentrations (usually determined in terms of 'x'). Depending on the size of k (if k is larger), then you may have to use the quadratic formula to solve for x. If the change in concentration is small, it can be ignored.

[Leonardo Le Merle 1D]

It's a good idea to memorize which bases and acids are strong so you can know exactly when to apply the above methods mentioned.

you have to use the ICE table

[Myka G 1l]

When using an ICE Table, can you ever have a starting value of products, or is it always 0?

Sometimes you will have a starting value of products and you’ll have to add x to the value in the ice table, creating a more complex equation that is equal to k. Also don’t forget coefficients in the ice table!

Use an ice table and any available information like the pKa or pKb as well as any equilibrium constants would be needed to solve such a problem
