Actually normality depends upon a simple formula that is :- Normality = Number of Gram equivalents / litre The term gram equivalents change as the valency of a substance changes . all the elements do not have same valence and hence it varies from element to element or molecule to molecule. And the term gramContinue reading “How does the normality of a mixture equation change for different solutes?”

what is valency ? how to calculate it?
Valency :- “It is the combining capacity of an atom”. it also indicates the number of electrons that can be gained , lost or shared . It decides that how many bonds can be formed, it gives the idea of molecule formation and the type of bond formed. calculation of valency is a simple taskContinue reading “what is valency ? how to calculate it?”
How to find a lone pair in simple way?
Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . Step2: make the bonds around the atom according to its valency and use the electrons for making the bonds. Step3: Now see if there are any unshared electrons pairs. These are your lone pairs. See theContinue reading “How to find a lone pair in simple way?”
