Experimental evidence about a new compound must be known before its formula can be determined should be discussed.
Empirical formula for some products like in precipitation reactions can be predicted if we have the details about the solubility. But some reactions produce products which haven’t been produced before. In such case, we need experimental evidences to predict the formula.
