I didn't get this question on the exam, and it's still not clicking for some reason. Can anyone help? (Feel free to explain as much of the basics behind all of this as you want!) Posting it below now:
" 'Hard Water' is classified as water having excess amounts of calcium and magnesium ions. Hard water causes scale to form, a conglomerate of CaSO4, CaCO3 and Mg(OH)2, and leads to trouble with domestic hot water heaters. Suggest a test for ONE of the cations in hard water that can help a homeowner deduce if they have hard water or not."
