What chemicals found in vinegar and salt clean coins?
Dirty coins like copper pennies lose their bright original shine because with time, the copper metal on the surface of the penny reacts with the oxygen in the air to form a dull brown copper oxide tarnish. Placing them in a vinegar salt (table salt or sodium chloride) solution is a way to restore the shine on dull pennies. The acetic acid in vinegar dissolves the copper oxide layer on the surface of the coin thus exposing the bright copper metal underneath. The reaction occurs much quicker if you add a little salt to the vinegar

The independent variable is also known as the experimental variable. It is the one variable that is manipulated or allowed to vary. All other variables are kept constant. For example, if you want to determine the relationship between mass and acceleration, you would vary the mass and it would be the independent variable. You would then measure the acceleration that occurs with different masses, which would be the dependent variable.
