SALTS EVERYDAY First some words about salts in chemistry. Salts are ionic compounds that can result from the neutralization reaction of an acid and a base. They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Salts can appear to be clear and transparent (sodium chloride)‚ opaque‚ and even metallic and lustrous (iron disulfide). In many cases the apparent opacity or transparency are

Salt of the Earth Flannery O ’Connor ’s novels and stories are inhabited with unique and flawed characters who are the result of O’Connor ’s satiric worldly perspective. While they are sometimes humorous‚ these misfits are usually unpleasant. Critics have termed them "grotesque‚" but O ’Connor has rejected this term because it suggests that the characters are too weird to belong in the real world. Instead‚ O ’Connor insists that the South is inhabited by many such people. For every good or evil

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

The effects of rock salt‚ which is used for melting snow in the winter time‚ works in a variety of ways. The main reason is to aid in melting of the snow making it easier for individuals to drive their vehicles and also the sidewalk for pedestrians. Overall‚ the rock salt used for melting snow‚ works but it have some pros and cons about it‚ but using it wisely should be the key to its success. Might grass growth be inhibited by salt? Introduction The usage of salt‚ (rock salt) is

The Effects of HGH (Human Growth Hormone) In Enhancing Performance and Side Effects of Its Prolonged Use Human growth hormone (HGH) is produced by the pituitary gland within the body. One of its main functions is to increase growth in children and adolescents as they get older. HGH also helps regulate body composition‚ body fluids‚ muscle and bone growth‚ sugar and fat metabolism‚ and in some aspects‚ heart function. Human growth hormone can also be produced synthetically. The synthetic form of

AN INVESTIGATION TO FIND THE EFFECT OF BILE SALTS OF ON THE DIGESTION OF LIPIDS I have investigated that if there is an effect of bile salts on the digestion of lipids in the milk. When lipids are broken down in to fatty acids and glycerol (see below)‚ the acid lowers the pH of the mixture. To help me determine and measure the digestion of lipids‚ a pH indicator phenolphthalein has been used to measure the pH of the mixtures. The pH indicator will change the colour from pink to either white (if

Income Inequality‚ Economic growth and its effects . Abstract “Some people are of the view that income inequality is a necessary part off the growth process‚ that it is generally unavoidable and that policy should focus on ensuring that everyone is doing better rather than focusing on narrowing the income gap” whilst other agrue that it hinders growth. This assignment was carried out to investigate and debate the theoretical and empirical views of the above statement as well as share my own

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked
