potato using Osmosis. I predict that the potato in the higher concentration of salt solution will lose an increasingly high amount of weight. I think this because the higher the concentration in salt‚ the more water particles will move through the potato cell’s semi-permeable membranes to try and balance the salt concentration. For example‚ if you placed a larger piece of potato into a beaker of an almost 100% salt solution; the potato would completely shrivel up because it would lose all of the

Egg flotation Objective/Question/Problem My objective is to see which egg will float. The question is how much salt is needed to be added to make the egg float. The problem is that I do not know how much salt is needed to make an egg float. Hypothesis If I add salt to the water then the egg will float because the egg has a density that is lower that the density of the fluid it displaces. Background Information If the object has a density that is higher than

temperature of higher salt concentrated water; what water has a higher boiling point. Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? The water with the most salt will have a lower temperature. Experimental Design List the materials used in this lab‚ and the procedure you followed. Materials: 1.salt 2. tap water

contact with oxygen‚ and water. They rust much faster when they are in contact with salt water‚ and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water‚ it causes the metals to rust. The metals we chose were iron‚ copper‚ lead‚ zinc‚ and aluminum. Those are some of the most commonly used industrial metals. We got the salt water directly from the beach‚ so that we would get the same reaction if this happened

Solubility Rules are as follows: 1. Salts containing Group I elements are soluble (Li+‚ Na+‚ K+‚ Cs+‚ Rb+). Salts containing the ammonium ion (NH4+) are also soluble. 2. Salts containing nitrate ion (NO3-) are generally soluble. 3. Salts

different concentrations of salt (NaCl) water. Problem: How do solutions of various salt concentrations influence osmosis in relation to an onion cell? Hypothesis What will happen to the onion cell if it is placed in salt water? What will happen to the onion cell if it is placed in distilled water? If ..the onion cell is placed in salt water then... the cell will shrivel up The independent variable is the salt solution and distilled water

Watch as it floats. 3) Put 4 tsp. of salt into the final glass stir it up and pour out some of the salt water. Now place an egg in the water. Slowly and carefully pour fresh water into the glass of salt water and watch as the egg sinks down till the middle. HOW IT WORKS: Density is the amount of space something

Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea‚ also known as the garden pea‚ is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect‚ the growth of the pea seed such as; temperature‚ moisture‚ planting depth and sunlight. The pea grows best in temperatures

The potatoes in 1% salt solution will get bigger. Isotonic is when the solution has equal amounts of solute inside and outside the cell. These are all different types of concentrations of solutions. The cell will not be affected at all. The potatoes in the 3% salt solution will have no change. If a cell is put
