Concentration is often defined by the number of moles per liter of a dissolved substance in a liquid. Variations include: ng/ml, ug/ml, mg/l, g/l. It really doesn't matter what the units are, as long as there are units for mass and volume.
This is a molar concentration.
Osmosis is defined as the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration, in order to equalize the concentration of solute on both sides of the membrane.
The pH level is defined as the log of hydrogen ion concentration. It is a measure of acidity of a solution.
journalism is a part of multimedia where in its concentration is on the field of writing.
The amount of a substance per defined space. Concentration usually is expressed in terms of mass per unit volume.
simple answer osmosis defined as the diffusion of water from a area of high concentration to a area of low concentration.
Yes, the pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. pH is defined as the negative logarithm of the hydrogen ion concentration.
Primary active transport is defined as utilizing energy in the form of ATP to transport molecules across a membrane against their concentration gradient. This means moving from a low concentration to a high concentration.
Normality of a solution is defined as the molar concentration divided by an equivalent factor
The pH is a measure of the activity of the ion H+ in a solution.
This is the molar concentration of the solute.
The acidic character increases with decrease in pH because the pH and acidity are both dependent on the hydrogen ion concentration, with pH being the negative log of the hydrogen concentration. So, at the concentration of H+ increases, the negative log of the H+ concentration decreases.
