How would the measured ph of the diluted material compare to the ph original diluted sample?

Answer:   hello my name is tink , i'm a greeter in training for welcome to & you for your question ; ) ! dilution reduces the ph of a basic solution. explanation: the ph of a basic solution is greater than 7. as you dilute a solution, it becomes more and more like pure water. so the ph moves closer to the ph of pure water, ph 7. the ph decreases on dilution. example: what is the ph of a 10⁻³ mol/l solution of naoh? what is the ph if you dilute 100 ml of this solution to 1 l?

Not a  mixture of two common elements that can be separated by physical means.

Ithink its called the coefficent.
