ABSTRACT
This project was done to determine the total hardness of ilara mokin water to show the usefulness of hard water in industries, environmental and social links.

INTRODUCTION:
WHAT IS HARDNESS OF WATER:
It is when water passes through or over deposit such as limestone; the level of Ca²⁻and Mg²⁺and HCO₃ ions present in the water can greatly increase and cause the water to be classified as hard water. This term results from the fact that cation and magnesium ions in water combine with soap molecules, making it hard to get suds.
High level of water ion such as Ca²⁻ and Mg²⁺ can cause scaly deposits in plumbing appliances & boilers. These two ions also combine chemically with soap molecules resulting in decreased cleansing. The American water works Association indicates that the ideal quality water should not contain more than 80mg/l of total hardness as CaCO₃. High levels of total hardness are not considered a health concern.
There are two types of Hardness:
Temporary hardness: this is due to the presence of bicorbonates of calcium and magnesium. It can be easily removed by boiling.
Permanent hardness: this is due to the presence of chlorides & sulphate of calcium & magnesium. This type of hardness cannot be removed by boiling.

MOTIVATION
I was bothered that the water in Ilara community doesn’t combine easily with soap leading to excessive consumption of WATER.

ENVIRONMENTAL SIGNIFICANCE:
Scales are formed as inner coating of the pipelines prevents corrosion
Absolute soft waters are

    Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent, impurities are easily dissolved. As water moves through soil and rock, it dissolves minute amounts of minerals and holds them in solution. Although it is not hazardous to health, hard water is a nuisance to both industrial and domestic water consumers. Mineral buildup on plumbing fixtures, poor soap and detergent performance, and a contribution…

    When water is heated limescale deposits can form, especially in machines such as fully automatic coffee makers, espresso machines and all hot water units. In this context you often hear about hard and soft water. The hardness of the water indicates the proportion of limescale. Your water supply company will provide more information about hardness of your water. If your groundwater flows through calcareous rock layers, eroded magnesium and calcium carbonate will cause limescale deposits in your water.…

    Boiling the water causes the precipitation of solid calcium carbonate or solid magnesium carbonate. This removes the calcium ions or magnesium ions from the water and so removes the hardness. Therefore, hardness due to Hydrogen Carbonates is said to be temporary. Calcium sulphate is slightly soluble in water when a river flows over Gypsum; it dissolves some of the rock. Therefore calcium gets into the water.…

    Experiments were done on the water quality and the contamination of groundwater. First, I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater, it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants by using a funnel to purify the water. The last experiment were performed using Dasani, and Fiji bottled water and Tap water to determine the quality of drinking water. I also predicted that tap water would leave the least amount of contaminants and the Fiji bottled water would have the most contaminants.…

    Usually, for heavy steel components, the hardness decreases at the core of component because the microstructure formed is ferrite and pearlite. While at the surface of the component have higher hardness. The difference of the hardness between the core and surface can be explained by Continuous Cooling Transformation or CCT diagram of the steel. If the cooling rate of steel does not cross the transformation curve of the diagram, then the hardness on the whole steel can be obtained.…
