Acids are substances that provide hydrogen ions (h +) and lower ph, whereas bases provide hydroxide ions (oh –) and raise ph the stronger the acid, the more.
Buffers work because they contain both positive [h+] ions, and negative [oh-] ions this allows them to donate [h+] ions to any potential base added, therefore.
