3. Water hardness refers to the
concentration of calcium and
magnesium ions in water. It is typically
measured in milligrams per liter (mg/L) or
parts per million (ppm). The presence of
these ions can lead to scale buildup in
pipes and appliances, affecting their
efficiency and lifespan.

4. There are two main types of water hardness: temporary and permanent.
Temporary hardness is caused by bicarbonates of calcium and magnesium, while
permanent hardness is due to the presence of sulfates and chlorides of these
minerals.
