Definition that contains positive ion
- double replacement reaction a chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound
- ionic bond a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion
- basic color a dye that is considered to be a base because the chromophore is part of a positive ion
- electrostatic bond a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion
- basic colour a dye that is considered to be a base because the chromophore is part of a positive ion
- electrovalent bond a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion
- acid hydrogen a hydrogen atom in an acid that forms a positive ion when the acid dissociates
- basic dye a dye that is considered to be a base because the chromophore is part of a positive ion
- ion engine a type of reaction-propulsion engine to propel rockets in space; a stream of positive ions is accelerated to a high velocity by an electric field
- acidic hydrogen a hydrogen atom in an acid that forms a positive ion when the acid dissociates
