What is the purpose of adding water to the base?
To prepare a dilute solution.
How do you we prepare cresol with soap solution?
cresol is prepared with soap solution as it is more soluble in the soap solution than water . moreover soap solution enhances its detergent and disinfectant properties.
What are the two form of hardness found in water?
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
How would you prepare a 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water?
You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride.
How do you prepare sea water solution?
Dissolve 30-40 g of sodium chloride in 1 L of water.
How do you estimate hardness of water?
The water supplier can provide you the details on hardness level if you are on municipal water systems, If you are using private water then you can get tested in laboratories. You can even measure it with water hardness testing kits which you need to purchase.

How do you lower hardness in pool?
If the calcium is a result of pool chemicals, draining some or all of the pool water will lower the calcium hardness level. If the cause is the fill water, commercial hardness reducers or chelating agents will bond with the calcium to keep it trapped in solution.
What is the difference between water and ecowater?
The main difference between water and ecowater is the hardness rating difference. For water testing and filter options, see your local water specialist.
