The key difference between burette and pipette is in their release mechanism. Burettes have a stopcock at the bottom while a pipette has a dropper like system that releases liquid in the desired amount by lessening the vacuum. Burette and pipette are measuring tools that we use in chemistry labs, to dispense liquids in measured […]

The key difference between conjugate acid and conjugate base is that conjugate acids donate protons, whereas conjugate bases accept protons. In 1923, two scientists, Bronsted and Lowry presented a theory on acid-base behaviour. According to Bronsted – Lowry theory, an acid is a proton donor, and a base is a proton acceptor. Therefore, a molecule […]

浓度和摩尔的关键区别ity is that the concentration is the content of solutes in a solution whereas the molarity is the method of expressing the concentration of a solution. Concentration and molarity are two important phenomena in chemistry. We use both these terms to indicate a quantitative measurement of a substance. If […]

The key difference between dilution and titre is that dilution is a chemical composition that we can easily change whereas titre is an exact value that we cannot change. In the quantitative chemical analysis, dilution and Titre are the two ways of describing the conditions, concentration or the percentage of particular particles, viruses, fats and […]

The key difference between hard water and soft water is that hard water contains lots of dissolved minerals such as calcium and magnesium whereas soft water has been treated, thus removing all minerals except sodium. The difference between hard and soft water is in their composition. Hard water contains a lot of dissolved minerals (mainly […]

The key difference between HPLC and GC is that HPLC uses a solid stationary phase and liquid mobile phase whereas GC uses a liquid stationary phase and gaseous mobile phase. HPLC and GC are both methods of separation of compounds from a mixture. While HPLC refers to High Pressure Liquid Chromatography, GC is simply Gas […]

高效液相色谱法和快速高效液相色谱的关键区别是that the pump pressure that we use for HPLC is around 40 MPa whereas the pump pressure for fast HPLC is around 3-5 MPa. The most common technique that we use for separating components of a mixture is “liquid chromatography”. There are several techniques to achieve […]

The key difference between molarity and molality is that molarity is the number of moles of solute present in 1 litre of solution whereas molality is the number of moles of solute present in 1kg of solvent. Molarity and Molality are measures of concentrations of solutions. The concentration of a solution gives the amount of […]

The key difference between bromocresol blue and bromocresol purple is that the colour change for bromocresol blue is yellow (acidic colour) to green (neutral) to blue (basic colour) while the colour change for bromocresol purple is yellow (acidic colour) to violet (basic colour). There are several compounds that we use to check the acidity or […]

The key difference between HPLC and UPLC is that the HPLC allows for the analysis of particles having their size around 5 micrometres whereas UPLC allows for much smaller particles around 2 micrometres. HPLC and UPLC are both Liquid Chromatographic techniques that are useful in separating the components of a compound. To know the difference […]
