How is the pH level of a substance affected by buffers and why are buffers important in the human body?
Because the cemicals such as litmus has a special acid in it that makes it change color to the level of pH i s in the substance Booboo Because the chemical litmus makes the pH paper change color according to the pH in the substance. the main reason for the change in color of pH paper is the presence of chemical known as flevin.
Acids do not simply "melt through" things. Various acids react with different materials. The stronger, more concentrated an acid is, the faster that reaction. pH is a measure of how strong an acid or a base is- the smaller the number, the stronger the acid. However, if an acid and a given material do not react (glass and sulfuric acid, for example) then no matter how strong the acid, there will be no reaction.
