ACIDS AND BASES (ALKALIS)
s- When atoms or groups of atoms lose or gain Electrons, they form charged particles called ions - either positively or negatively charged

*ACIDS:
s- Acids are Proton donors as they will react to lose Electrons to form positive H+ ions
- These H+ ions make the Aqueous Solution Acidic

*BASES (ALKALIS):
s- Bases (Alkalis) are Proton acceptors as react to gain Electrons to form negative OH- ions
- These OH- ions make the Aqueous Solution Alkaline
OH- ions make the solution alkali (not acidic).
ReplyDeleteThere is a big ERROR..... The H2O is not gaining electrons, it is only gaining a single proton from the hydrogen ion. This is why it is called a proton donor; it is the ion H+ that has no electrons which is gained by the H2O, not the electrons. Otherwise we would call it an electron donor, not a proton donor.
