Salinity is the measure and concentration of all the salts dissolved in water. Usually measured in parts per thousand (ppt or )‚ ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less (University of Rhode Island). Many factors go into salinity‚ making water salty. To name a few‚ salinity affects the environment through sediment from rocks washes into the ocean‚ evaporation of ocean water‚ and sea ice formation are known to increase the salinity of the ocean (NASA). It

Kalacas*‚ Hanna Mae Laluces‚ Ina Bianca Lanuza Department of Chemistry‚ College of Science *Corresponding author; e-mail: knight_BeNcH66@yahoo.com Abstract Chromatography is a powerful technique for separating and/or identifying the components in a mixture. There are different types of chromatography and each has its own strengths and weaknesses. In this experiment‚ pigments of the

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

Title: Candy Chromatography Background Information and Research: Paper Chromatogrpahy is a analytical method that is used for seperating and identifying mixtures of color. There are two stages‚ the stationary phase and the mobile phase. The first is for a solid and the second for a liquid or gas. -Reference http://www.chemguide.co.uk/analysis/chromatography/paper.html Purpose: To see how paper chromatography works.

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source
