Question

Quizplus · Accepted Answer

A chelator is a substance that binds to metal ions such as calcium, preventing them from participating in chemical reactions. Chelators are used in research and medicine to remove excess metal ions from the body, and to study the role of metal ions in biological processes. In this case, the best answer is C, as it accurately describes the role of a chelator in binding to calcium ions to remove them from solution. The other options are incorrect, as they either describe substances that precipitate or degrade cells, or add calcium ions to a solution, which is the opposite of what a chelator does.
