Chromium cation or anion
WebJul 8, 2024 · Cation exchange is useful for water softening by removing hardness ions such as calcium and magnesium. It can also remove other positively charged contaminants including barium, radium and strontium. Treatment capacities for different contaminants vary depending on the properties of the resin used and characteristics of the influent water.

WebColumns: The chromatography column is the heart of the IC analysis. There are two types of IC columns for anion analysis: carbonate optimized columns and hydroxide selective columns. Carbonate optimized columns are suited for isocratic separation of anions in simple matrices using carbonate or carbonate/bicarbonate eluents.

WebNov 29, 2016 · Cr (CO 3) 3. This is an ionic compound. Chromium is a transition metal cation and CO 3 is an anion with a charge of 2-, as said in my chemistry textbook. And since CO 3 has a charge of 2-, the over all charge of CO 3 would be 6-, since it has a subscript of 3 in the bolded formula above. So my guess is that since Chromium has no … Web(b) A sodium cation (Na +) has lost an electron, so it has one more proton (11) than electrons (10), giving it an overall positive charge, signified by a superscripted plus sign. You can use the periodic table to predict whether an atom will form an anion or a cation, and you can often predict the charge of the resulting ion.
