Sodium hydroxide will raise the pH of water and do a few things. As the pH is raised above 7 it will begin to eliminate carbonic acid. (2NaOH + H2CO3 >> 2H20 + 2NaCO3)
Hard water is composed of a soluble form of calcium and magnesium and some iron. The calcium and magnesium are in the form of bicarbonates.
The sodium hydroxide pulls hydrogen from the bicarbonates and converts them to insoluble carbonates. They then fall to the floor of the treatment vessel.
(2 OH- + Ca(HCO3)2 >> 2H2O + CaCO3
Magnesium can take the place of Calcium in this reaction.
All of this caused by atmospheric carbon dioxide dissolving things like limestone.

What is the purpose of titrating sodium hydroxide with an acid solution?
Determination of the concentration of sodium hydroxide in solution with the help of a neutralization reaction.
How does storing water in reservoirs help to purify water?
Water is stored in a reservoir until needed. While stored, particles of dirt settle at the bottom. This helps to purify the water.
How do you use purify in a sentence?
This eucalyptus ointment will help to purify the air.
How does NaOH help in pH regulation?
Sodium hydroxide, NaOH, has a very high pH, so it can be used to raise the pH of some mixture that is too acidic.
What function of sodium hydroxide as solvent?
Aqueous Sodium Hydroxide (NaOH) can be used as solvent to help dissolve water insoluble compounds that have an acidic functional group. NaOH reacts with the acidic functional group and forms a water soluble salt. For example, consider R-COOH to be a water-insoluble carboxylic acid. When R-COOH is added to the aqueous NaOH, the following reaction occurs: R-COOH + NaOH(aq) -> R-COO- NA+ + OH- + H3O+ The above reaction produces R-COO- NA+ which is a water soluble salt. This process is sometimes called water solubility by salt formation.
What is the purpose of titrating sodium hydroxide with an acid solution?
Determination of the concentration of sodium hydroxide in solution with the help of a neutralization reaction.

How does storing water in reservoirs help to purify water?
Water is stored in a reservoir until needed. While stored, particles of dirt settle at the bottom. This helps to purify the water.
What is an example of a hydrous salt?
An example of a hygroscopic salt would be calcium chloride, a salt that absorbs water from the atmosphere to form a saturated solution
How does chlorine help purify water?
chlorine kills off all bacteria within the water
Why is sodium hydroxide often used in oven cleaners?
Because it is a base and bases help to clean things.
What does sodium hydroxide do in toothpaste?
Sodium hydroxide becomes very alkaline when dissolved in water, so it is used to neutralize the acidic pH imbalance caused by the other chemicals used in most toothpastes. Its common name is "lye" and it can be toxic if ingested. Therefore, toothpastes that contain sodium hydroxide often have a warning label that advises consumers to get medical help or contact a Poison Control Center right away "if more than used for brushing is accidentally swallowed".
How do ultraviolet rays help to purify water?
Ultraviolet rays kill harmful germs present in the water, hence purifying it.
Can water lilies be used to purify water for recycling?
Yes water lilies absorb nutrients that could cause algae bloom. They do help purify water.
