Ions class 8
WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion concentration. The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although ... WebSolution Verified by Toppr An ion is an atom or group of atoms where the number of electrons is not equal to the number of protons. That means when a stable atom gains or loses an electron, it becomes an ion. Examples of ions are as follows: H +,Na +,Ca 2+,F −,O 2− Was this answer helpful? 0 0 Similar questions Assertion
