to accept a pair of electrons. They will grab an electron pair from any substance added to the solution and corrode the substance. Corrosiveness is a characteristic of acids. Thus, due to the higher concentration of hydrogen ions than that of the hydroxyl ions, the solution becomes acidic. ...
An amphoteric substance is one that can act as either anacidor abase, depending on the medium. The word comes from the Greekamphoterosoramphoteroi,meaning "each or both of two" and, essentially, "either acid or alkaline." Amphiprotic molecules are a type of amphoteric species that either ...
An acid is a substance that, when mixed with water, becomes a hydrogen ion donor, while a base, when mixed with water, becomes a hydrogen ion acceptor. The pH scale helps us to measure whether a substance is acidic or basic. The lower the pH, the stronger the acid. The higher the ...
Solvent is a chemical substance in which a Solute is dissolved to form a Solution.It is a component of a solution that ispresent in the largest amountand is used to dissolve the solute. Solvent is a substance that is used to dissolve another chemical substance, called a Solute, to form a...
Furthermore, when an acidic substance loses a proton, it forms a base, called theconjugate baseof the acid. When a basic substance gains a proton, it forms an acid called theconjugate acidof a base. Examples of Brønsted-Lowry Acids and Bases ...
for one, vinegar is an acetic acid solution in water. it can be impossible to tell which substance is the solute and which is the solvent in a two-liquid solution. in addition, the solvent is the material found in the largest quantity. in vinegar, the solvent is water and the solute ...
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 it depends on how a solid or liquid substance interacts with water when mixed ...
This magnesium oxide is an entirely new substance. Thus, a new substance is formed during the burning of magnesium ribbon. So, the burning of magnesium ribbon is a chemical change (see Figure). We can perform the magnesium ribbon burning activity as follows....
An alloy is a substance made bymeltingtwo or moreelementstogether, at least one of themmetal. An alloy crystallizes upon cooling into asolidsolution,mixture, or intermetalliccompound. The components of alloys cannot be separated using a physical means. An alloy is homogeneous and retains the proper...
Greenhouse effect: The warming of Earth's atmosphere as the result of the capture of heat by carbon dioxide molecules in the air. Oxide: An inorganic compound whose only negative part is the element oxygen. Oxygen-demanding agent: Any substance that reacts with oxygen dissolved in water. ...
