Explanation:
Gas is the state of mater which changing its shape and volume according to the volume and shape of container.
Properties of gas:
Molecule of gases randomly move everywhere and occupy all available space.
Gases don't have definite volume and shape and take the shape and volume of container in which it present.
Their densities are very low as compared to the liquid and solids.
Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.
The very weak inter molecular forces are present between gas molecules.
The Ph of tomato juice is calculated as follows
Ph = -log (H+)
if H+ ion concentration is 10^-4
Ph is therefore = -log (10^-4) =4
the tomato juice has a Ph of 4
