What is Mixture ?
A Mixture is a solution containing two or more products (we can simply call these products as Elements of the mixture) which bear a certain proportion to each other by quantity. This may be expressed in terms of
- Percentage (ex : 25% of salt in water)
- Fractions (ex : A solution of water and milk such that: water : milk = 5:7)
When you add two mixtures, the respective quantities of these elements of the mixtures get added, thereby affecting the overall contents of the combination. So, the resultant mixture would have “a weighted proportion” of the two elements.
It is presumed that NO CHEMICAL REACTION takes place while the two mixtures are combined. So these are physical mixtures rather than chemical mixtures. (This clarification is for those chemical geniuses who thinks about EVAPORATION 😉
