The common-ion effect can be understood by considering the following question: What happens to the solubility of AgCl when we dissolve this salt in a solution that is already 0.10 M NaCl? In the table below, compare the differences in effect between point mutations and chromosomal mutations. This phenomenon is called "the common-ion effect". email. 1 decade ago.

This isn't really a common ion effect question, because there is no common ion present. Practice: Solubility equilibria questions. Next lesson. Ionizing radiation is a high-energy form of radiation which can cause ions or free radicals to form. What minimum OH¯ concentration must be attained (for example, by adding NaOH) to decrease the Mg 2+ concentration in a solution of Mg(NO 3) 2 to less than 1.1 x 10¯ 10 M? I hope this illustrates and explains your question. Hello, After reading the solution to the question, my first question is a) How is molarity of 0.033 M of 2.5 mmol of \(NH_4^+\) ions and 2.5 mmol of \(NH_3\) molecules computed?
