A solution containing which one of the following pairs of substances will be a buffer solution? A salt and an acid, or two acids? In this post we’ll discuss what it means for a solution to be a buffer.
The two acids must have the same number of protons. For example if one acid has a hydrogen and an oxygen atom with five electrons, then so does the other. These atoms will form ions that are equal in charge to prevent any changes to pH levels when they come into contact with each other.
This is because balance between acidic and basic compounds keeps pH at seven on a scale from zero (0) which indicates pure acid, up to fourteen (14), or 100% base solution. Buffer solutions allow for this balance without sudden fluctuations in either direction by using substances like salts or weak organic molecules as buffers which react quickly enough with both types of compound, but not too fast so that reactions cannot occur as needed. Buffer solutions maintain
