Listenwhich change in the h+ ion concentration of an aqueous solution represents a decrease of one unit on the ph scale?

Explanation:

The pH scale is a logarithmic scale that runs from 1 to 14.

1 is the lower limit of the scale and 14 is the upper limit of the scale. On a pH scale, to represent a decrease of one unit, the concentration of the hydrogen ion or the hydroxyl ion must change.

A decrease in 1 unit or 1 pH represents a concentration of 10moldm⁻³.

                    Note: pH= -log₁₀[H⁺]

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
