M2vpavogadro's Theory Of Dilution

A dilution is created when two solution are mixed together to reduce the concentration, or when water is added to a solution for the same reason. Molarity is the amount of molecules that a substance contains, for example, the amount of sodium ions in water after adding 2 grams of salt or the amount of sodium chloride molecules to in 10 grams of salt. The reason that we need to understand the molarity of a substance is to have a more controlled experiment. When the molarity of a substance is known, then a person knows how much of a substance if required to create a complete reaction in which all compounds that have to react do so and there is a small amount of them left in case too much of one substance is used. It’s also important to know dilutions for safety reasons. For example, it is safe to drink Clorox if it is diluted enough but it could be very dangerous …show more content…
A series of dilutions will occasionally start mixing water with a small amount of solution then adding more and more solution at a constant factor until the desired amount of different concentrations is acquired.
Avogadro’s theory of solution is simply another extended way of his hypothesis to dilute solutions which is expressed as M1V1=M2V2 (Meldrum 48). The equation is the way to find the concentration of a substance, but the molarity of at least one and the volume of both are required.
Avogadro came up with the value of a mole which is 6.022 x 10^23. This means that one mole of something – an element or compound – contains 6.022 x 10^23 molecules or atoms. For example, one mole of carbon 12 has that amount of atoms, also the mass of one mole is equal to the atomic mass of an element (Chem Team). The mole is also used to balance chemical equations which goes back to knowing the amounts of solutions required to create a reaction with the least amount of both
