The Chemistry Of Water Essay

517 words - 2 pages

A water molecule consists of one atom oxygen with two atoms of hydrogen connected to it forming a “V.” HOH is a polar molecule with means that charges unequally form around it. This distribution of charges creates a negative charge on the oxygen side and a negative charge on the side with the hydrogen atoms. This creates hydrogen bonding which gives water its unusual characteristics. Hydrogen bonds are weak temporary bonds that form when the positive part of one water molecule attracts a negative part of a different water molecule. Hydrogen bonding makes water have unusual properties that also make life possible on earth.Hydrogen bonding causes water to be cohesive, which basically means it sticks to itself in liquid form. Hydrogen bonds connect one water molecule to the next, to the next, and so on. This is an important property because trees use it to get water and nutrients to the higher parts of the tree. When water evaporates off of leaves water is being pulled from the trunk into where the water has evaporated from. This pulling force exerts all the way to the roots. The water brings along important nutrients also. This process is called capillary action. Surface tension is also formed because of cohesion. Water molecules along the surface of the water are not fully surrounded by other water molecules so they form more bonds along the edge of the water. This allows certain insects, such as the water strider to stride across the water.Water’s high specific heat or its resilience to...

The chemistry of shampoo Essay

1583 words - 6 pages surfactants. The major types of surfactants are anionic, cationic, nonionic, and amphoteric. Surfactants with a positive charge are called cations, and ones with a negative charge are called cations. An example of this would be sodium chloride. Sodium forms positive ions upon dissolving in water, while chlorine makes negative ions. They attract to each other. Surfactants tie in with shampoo and all other hygiene products, because anionic surfactants

The Properties of Water

1103 words - 4 pages Water is not as simple as people think it is. Water is formed by the bonding of two hydrogen atoms and one oxygen atom. This bond that is being referred to is termed as a polar covalent bond. Polar means having a pair of equal and opposite charges. In this case, that is exactly what is happening. The oxygen atoms are negatively charged, whereas, the hydrogen atoms are positively charged. Water is formed when one atom of oxygen
