Solutions in Chemistry free essay sample

Increasing the pressure causes the solute to be increased in the solvent, because the pressure forces the remaining gases into the solute. Therefore, pressure increases the solubility of the solution. Increasing the temperature causes the molecules to gain energy; the solvent molecules contact the solute particles more frequently. Increased surface area means that more of the solute is exposed to the solvent, dissolving the solute more quickly. 2 As stated above, the combination of solvents and solutes result in a solution. The solution then has a certain concentration. There are a number of ways to measure the concentration of a solution. There is molarity, parts per million, grams per liter and percent composition. To find the molarity of a solution, you just simply divide the moles of the solute by the liters of the solvent (moles/liters). Percent composition is calculated by dividing the mass of the compound by the total mass (mass of compound/total mass). We will write a custom essay sample on Solutions in Chemistry or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Parts per million is calculated by finding the mass of the solute in grams and dividing it by the mass of the solvent and solute in grams, and then multiplying it by one million ((grams of solute/grams of solvent+solute)*1,000,000). A certain species of crabs are kept as pets. These crabs are usually salt-water creatures. The owner must realize that this creature must live in a solution of salt water. Salt being the solute and water being the solvent. When combined, these two will make a solution: salt water. Perfect for the crab to live in. However, if the water is too salty, or not salty enough, the crab will most likely die due to the unsuitable environment. The crab can only take so much concentration of the salt water. The owner must use one of the calculations such as molarity to figure out a suitable concentration of salt water for the crab to inhabit. The crab then can survive in the salt-water environment. Another scenario may be when a mother is making lemonade for her children on a hot day; she has to know how to comprise a solution of lemonade. She must realize that lemon water is the solvent and sugar is the solute. If shes smart, shell figure out the molarity of the perfect mix of sugar and lemon water to make the finest of lemonade. 3 Solutions are everywhere, not just in a chemistry classroom. As portrayed above, these things affect everyday life. Solutions are mixes of solvents and solutes. Solutes get dissolved and solvents are the ones doing the dissolving.
