Examples of quantitative observations include the following: “the melting point of crystalline sulfur is 115.21° Celsius,” and “35.9 grams of table salt—the chemical name of which is sodium chloride—dissolve in 100 grams of water at 20° Celsius.” For the question of the dinosaurs’ extinction, the initial observation … What is the best definition of observation? […]
Filter paper has thousands of tiny holes that allow the liquid molecules to pass through. The filtered liquid is called the filtrate. The larger solid particles, in this case, the sand grains are unable to pass through and are left on the paper. And we call this the residue. What is filter paper called in […]
Emulsifiers work by forming physical barriers that keep droplets from coalescing. A type of surfactant (see Sidebar), emulsifiers contain both a hydrophilic (water-loving, or polar) head group and a hydrophobic (oil-loving, or nonpolar) tail. Therefore, emulsifiers are attracted to both polar and nonpolar compounds. What is an emulsifier easy definition? An emulsifier or emulsifying agent […]
A good buffer generally contains relatively equal concentrations of a weak acid and its conjugate base. Many different factors must be considered in choosing a good buffer, the most important being the ionic strength and the UV absorbance at low wavelength. How do you determine the best buffer? (1) The pKa of the buffer should […]
Ethanol, also known as ethyl alcohol, is a colorless flammable liquid that has a pungent taste. Produced by fermentation, it is the alcohol found in alcoholic beverages and used as a solvent.

Ions, or charged atoms, have superscripts, or tiny numbers above the element’s symbol, and they show if an atom has gained or lost electrons. A positive superscript means the atom lost electrons whereas a negative superscript means it gained electrons. For example, Ca +2 lost two electrons. What is a subscript used for in chemistry? […]
Initiators trigger chemical reactions. They are not true catalysts, as they become an integral part of the end product; because of this they are instead considered to be co-reactants. Reaction accelerators are catalysts which quicken the progress of a chemical reaction. What is initiator and inhibitor? If the radical reacts with another radical to give […]
