Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

Salt is made up of 40 percent sodium and 60 percent of chloride‚ is a very important part of daily lives as it helps maintain your blood’s water content‚ balances acids and bases in your blood‚ and it helps in the movement of electrical charges which are in your nerves throughout your muscles. A human being should consume about 2400 mg of salt daily. On average‚ humans tend to go over the recommended amount. The food industry adds 75 percent of the sodium that we humans consume.

Robert Lawrence and Edmund Stephens‚ two graduate students of geology from Columbia University‚ organized the Saline Salt Company in 1974. Keeping in mind the fact that every 1‚000 grams of seawater contains approximately 35 grams of various salts‚ the two men pictured limitless wealth for themselves by extracting these salts. Common table salt comprises 27 grams out of each 35 grams and is easy to extract; so‚ the men decided to begin producing it. They picked New Iberia‚ Louisiana as the ideal

Michael Tarabula 11-3-2005 Jethro Tull’s Seed Drill Jethro was born in Basildon‚ Berkshire in 1674. He is widely known for his invention of the seed drill that improved agricultural ways greatly. The seed drill prevented farmhands from broadcasting the seed‚ which is just throwing the seed out in no form‚ and made it where the seeds were put in orderly rows. The seed drill allowed the farmers to make rows of seeds instead of broadcasting. This made it easier for farmers to weed

Acid rain effects the growth or germination of plants. In this experiment we are testing if acid rain effects the growth or germination of common pea seeds. The independent variable in this experiment is the replica of the acid rain (or the PH level)‚ while the dependent variable is the growth/and or germination of the pea seeds. This is a common problem in our environment today as rain continually gets more acidic. Our hypotheses in this experiment were that the growth of the pea seeds in the experimental

known as common salt. It is important because it is essential to the health of human beings and of animals. for domestic use it is fined down to what is known as table-salt‚ and small quantities of other chemicals are added to it to keep it free-flowing when in contact with the atmosphere. Salt and potassium are combined to produce iodised salt‚ used when iodine is lacking in diet. It’s absence cause goitre‚ the swelling of the thyroid gland.

questions on the effects of salt on grass growth. In the winter‚ many people place a salt compound on their driveways to melt snow and ice that has accumulated. The following spring‚ it is noticed that the edges of the driveway does not have any grass growing and grass a little further from the driveway is growing slower than the rest of the lawn. It will be determined if grass growth is negatively impacted in the spring after a winter of salt compound applications. Salt and Grass Growth

Salt i. scientific - I think that scientifically building this on the salt marsh is unacceptable. We know that there are thousands of organisms inhabiting it‚ and they`d all be destroyed during the process. The benifits are endless of a salt marsh‚ but include the fact that it is protecting us from possible floods‚ seeing as we live beside the ocean‚ and a river. Filtering our water‚ and like I mentioned‚ it`s home to many organisms. ii.économique - Economically the benifits of this project
