Why is degree of dissociation used to estimate strength of an acid?
1 votes

I would answer only the constant of dissociation $K_a$, because it is a thermodynamical constant and you can calculate it from potentiometric measurements without dealing with activities and so on. If ...

Confusion regarding orbital, electron and Quantum no’s
1 votes

An orbital is the region of space, in which an electron has a probability at least of 95% be present. The quantum numbers give the following information: $n$ is the principal quantum number and it is ...

What is the mathematical meaning of the plus sign (+) in chemical reaction equations?
0 votes

The plus sign in chemical reactions manifests the mass conservation. If your reactant mixture has a mass of 1 kg (it is just a random number), then also the product mass will have the same value. ...
