“Road salt” is a common term used for some chloride salts‚ including sodium chloride (NaCl)‚ which are used as de-icing agents on roads. The application of these de-icers on roads and other impervious surfaces in North America during winter months was in practice since the 1960s. The amount of snow fall is so high in these areas that snow and ice management becomes very essential to prevent road accidents‚ to maintain a continuous flow of traffic and to ensure safe pedestrian travel during winter

the additional of salt (Bylund‚ 1995). Salt (Sodium Chloride) is used as flavoring and preservative as it inhibit the microbial growth. Salt content in butter is limited by legislation in some countries. For example‚ in Thailand‚ the maximum sodium chloride content in butter shall not exceed 4 percent of total butter weight (Thai Ministry of Public Health‚ 2001). Therefore‚ analytical methods are required to determine the salt content in butter product. In this experiment‚ salt was extracted from

It is clear that salt‚ also known as sodium chloride‚ should no longer be used on our roads in the winter months. The first two reasons why salt needs to stop being used are because salt negatively affects aquatic ecosystems and causes damage to vegetation. The third reason is because thankfully‚ there are alternatives that we can use‚ that would be benefiting us which we should use instead of sodium chloride. To begin with‚ sodium chloride is detrimental to our aquatic ecosystems when it is

Salting an egg is a very evident process. First‚ you must mix the clay‚ the salt‚ and the water. The clay that you must be used is from ant hills or termite mounds; also the kind of salt that must be used is table salt. You must used the ratio 1:1:2 in mixing the clay‚ salt‚ and water until the texture of the admixture becomes smooth and forms a thick texture similar to cake batter. Step two is to dip the fresh eggs in the admixture and packed in a box. Fresh duck eggs are must be used in dipping

Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame. HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner‚ then the colour given off by the flame is due to the metal part of the salt. METHOD: (1) With a heat proof mat under the Bunsen burner‚ turn the gas on and light up the Bunsen burner with matches. (2) Pour enough Hydrochloric acid into a beaker. (3) Using your wire‚ dip it into the beaker containing Hydrochloric

The floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount
