Lab 4: Photosynthesis and Chromatography of Spinach Leaves Discussion: The chromatography of the spinach leaves was taken to establish what pigments were present in the chloroplasts of the leaves. The solvent carried and separated the different pigments up the cellulose paper. The solvent moved up the paper because of capillary action because of adhesion of the solvent molecules and the paper. The pigments dissolved in the solvent also were carried up the paper and were separated because

*ABSTRACT: There are many kinds of ink. In our experiment we will use Ti plant as the main component of our ink. Having two different set-ups will provide the chance to compare the colors and consistencies. Cornstarch is an efficient additive to have the right consistency of the product. Also vinegar is also efficient‚ though there is no obvious change in color‚ it was seen that it gave the ink a consistent color whether wet or dry. We also add some herbs which helps our product to look more darker

cakes. The cherries will act as the main component of the ink. The researchers will also add vinegar and salt to the mixture of the cherries. The vinegar and salt will clarify and deepen the color of the ink as well as preserve the mixture from spoiling. The equipment that will be used by the researchers is within their financial capability and it can be completed within a reasonable period of time. The researchers will be trying to make ink made of cherries. The set up will be mashing the cherries

is our project. If our markers will ran out of ink‚ we don’t need to buy a new one‚ because all we have to do is use seaweed and mix it with the other materials stated in Chapter 2. Because of this project‚ we can save more and spend less. Statement of the Problem: Most people in school‚ particularly the students and the teachers‚ needs markers for our reports‚ projects‚ and etc. But one of the problems in using markers is they ran out of ink easily. Because of that‚ we need to buy again a

How to Make Ink from Alugbati Things You’ll Need: • Fresh fruit of alugbati • Mortar and pestle • Strainer • Bowl • 3 tbsp. vinegar • 1 tbsp. salt • 2 tbsp. rubbing alcohol • 1 tbsp. iodine • Bottle Writing ink can be made from many natural sources‚ such as the fruit juice of the alugbati plant. Alugbati‚ known in the U.S. as Malabar spinach‚ is commonly grown for its soft‚ spinach-like leaves and shoots. Alugbati is of African and East Asian origin. The juice of the fruits was reportedly

Magnetic ink is very useful because it is readable both by humans and by specialized equipment. It is one of the components that makes it possible to process personal checks securely‚ quickly and accurately. Magnetic ink character recognition (MICR) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents. The MICR encoding‚ called the MICR line‚ is at the bottom of cheques and other vouchers and typically includes

Paper chromatography Presented by – Miss. Shruti Vilas Kharat. SYBSc / FS13164 History- Paper Chromatography (PC) was first introduced by German scientist Christian Friedrich Schonbein (1865). PC is considered to be the simplest and most widely used of the chromatographic techniques because of its applicability to isolation‚ identification and quantitative determination of organic and inorganic compounds. Definition- Paper chromatography is an analytical method technique for separating and

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to
