Acids. Acids are substances that give H. +. ions when added to water.. Alkalis. What are we testing to find?. Precipitate tests are used to detect the presence of an ion within a solution.. Precipitate tests may test for positive ions, for example magnesium ions (Mg. 2+. ). . Positive ions are called . Precipitation part 2. Predicting the Formation of a Precipitate. Objective. I can use the solubility rules to predict the precipitate formed in precipitation (double replacement) reactions. Precipitation reactions. Arnaldo Negron Marty; April 24, 2014. 1. Objectives.
