A solute is defined as the substance that isdissolvedin asolution. For solutions of fluids, thesolventis present in greater amount than the solute.Concentrationis a measurement of the amount of solute present in a chemical solution, with respect to the amount of solvent. Examples of Solutes Usu...
An acid is a chemical species that donatesprotonsorhydrogenionsand/or acceptselectrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and...
A series of free IGCSE Chemistry Activities and Experiments (Cambridge IGCSE Chemistry). This experiment investigates the effect of concentration on the rate of the reaction between sodium thiosulfate and dilute hydrochloric acid. The rate of reaction is measured by timing the disappearance of an × ...

Mole fraction may be a unit of concentration in chemistry. A mole is really a variety of molecules, approximately 6 × 1023. A mole fraction is the ratio of molecules of 1 component during a mixture. For instance, if the mole fraction of methane in gas is 0.90, then this suggests that...
The solute concentration is defined as the amount of mass (grams) of the solute per unit volume (liters) of solution. The maximum possible solute concentration in a given solution is called the solute solubility. The solubility of a solute is the maximum amount you can dissolve in the ...
A solute (e.g. solid, liquid, gas) is a substance that is being dissolved, occurring in a smaller quantity. On the other hand, a solvent is a substance that does the dissolving and occurs at a greater concentration. Once these two are mixed, the solution follows the physical state of ...
What is a dynamic equilibrium in chemistry? The word dynamic means continuous change. Dynamic equilibrium in chemistry means that reactants are constantly forming products and products are constantly forming reactants. Since the rates of formation are identical, the overall concentration of each chemic...
pH is the measure of how many H+ ions are present in terms of concentration. The higher the concentration of H+, the more acidic the solution is. The lower the concentration of H+ and the higher the concentration of OH-, the more basic it is. This makes pH a chemical property because...
