base
1. Precipitation
To determine the term for a reaction that results in the formation of an insoluble salt, you need to know that a salt is formed when the positive ion of one compound combines with the negative ion of another compound. An insoluble salt is one that does not dissolve in water. Therefore, the term you are looking for is "precipitation." In a precipitation reaction, an insoluble salt is formed as a solid product.
2. Dissociation
To find the term for the process in which ions within an ionic substance are separated, you need to understand that in an ionic substance, the positive and negative ions are held together in a lattice structure. Dissociation is the term used to describe the process when an ionic compound breaks apart into its constituent ions when dissolved in a solvent, typically water. This separation into ions allows the ionic substance to conduct electricity in solution.
3. Cation
To determine the word for the positive ion, you need to know that ions can be either positively charged (cations) or negatively charged (anions). Cations are formed when an atom loses one or more electrons, giving it a net positive charge. For example, sodium ion (Na+) and calcium ion (Ca2+) are both cations because they have a positive charge.
4. Base
To identify a proton acceptor, you need to understand the concept of acids and bases. In the Brønsted-Lowry theory, an acid is defined as a proton (hydrogen ion, H+) donor, while a base is a proton acceptor. Therefore, the term you are looking for is "base." Bases are substances that can accept protons from acids to form a new compound. Examples of bases include hydroxide ion (OH-) and ammonia (NH3).
