Problem 101AE

Problem 101AE

Hard water contains Ca2+, Mg2+, and Fe2+, which interfere with the action of soap and leave an insoluble coating on the insides of containers and pipes when heated. Water softeners replace these ions with Na+. Keep in mind that charge balance must be maintained.

(a) If 1500 L of hard water contains 0.020 M Ca2+ and 0.0040 M Mg2+, how many moles of Na+ is needed to replace these ions?

(b) If the sodium is added to the water softener in the form of NaCl, how many grams of sodium chloride are needed?

Step-by-Step Solution:
Step 1 of 3

 Matter  Has three forms  Solid  Liquid  Gas  Composed of Atoms  The smallest particle that makes up the chemical properties of elements  Contains 3 subatomic particles  Protons  Positive charge  Weighs 1 amu  Electrons  Negative charge  Equal to proton number  Neutrons  Neutral charge  Weighs 1 amu  Atomic mass-atomic nu,ber  Elements  Periodic Table organizes them  Chemical Symbol  Different one for all elements  Usually first letter  Atomic Number  Number of protons  Arranged by atomic number
