What is polarity? and i need an example on it

Polarity is the dipole-dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule

An example is H2+ (SO4)2- in Tetraoxosulphate (VI) Acid

Explanation:

In the acid H2SO4, ionization results in the formation of a Positively charged hydrogen ion (2H+) and a negatively charged Sulphate ion (SO4)2-

The slightly positive and negative parts in the ACID generates the DIPOLE (two poles) and THUS explains polarity

im sorry for wasting your time but i have -75 points some how and i think its a glitch

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
