Anthocyanins (Figure I) are responsible not only for the red and purplish colors of autumn‚ but also for similar colors in various summer leaves (red cabbage‚ red lettuce‚ red plum tree)‚ flowers (roses‚ hydrangeas‚ geraniums‚ bachelor buttons‚ dark pansies)‚ fruit (cherries‚ red apples‚ grapes‚ tomato‚ blackberry‚ blueberry‚ plum)‚ roots (beets‚ radishes)‚ bulbs (red onions)‚ and petioles (rhubarb).

to use the pH balance scale to determine Acid‚ Base‚ and Neutral. On this lab we used 7 different solutions to determine if it’s either base‚ acid‚ and neutral. These are ammonia‚ vinegar; drain cleaner‚ soft drink‚ baking soda‚ detergent‚ and lemon juice are the solutions that are going to be tested in this lab. My hypothesis for these solutions is ammonia is acid‚ vinegar is neutral‚ drain cleaner is base‚ soft drink is base‚ baking soda is base‚ detergent is base‚ and lemon juice is an acid

While working with tomato‚ I realized that they grow best at around pH 7. Perhaps‚ it might work well with Rhododendron too!” “Oh‚ you might be right‚ I’ve read that pH affects the intake of the nutrients of plants‚” Dr Ong exclaimed. “I think I have to agree with you‚” replied Christopher. “I forgot to mention that the plot of land is on one of the roof top garden

A pH of 7 is neutral and the color is green. When a pH less than 7 it is acidic. When pH greater than 7 it is an Alkali. The picture below shows the pH scale and what is weak and what is strong. The easiest way to measure the pH number of the acid is to use a universal indicator. There are three different types of indicators‚ like the main type universal indicator. Then the red cabbage indicator and the litmus paper. Litmus paper indicator

My first literature review will come from a blog titled‚ “How Can You Tell If Something Is An Acid Or A Base?” The article explains how water’s elements form it and also how pH in acids and bases abide by certain laws and situations. Acids and bases are normally found in a liquefied state forming molecules that would dissolve in water to let out ions. Acids normally are spoken of as giving a hydrogen ion to a solution while

color. A change in the pigments will cause the light to reflect differently and a color change to occur. Testing for pH is an example of a color changing reaction. The pH of the solution will change the pigment on the litmus paper or in the indicator. Acids and bases change the pigments in different ways‚ which causes the indicator to change different colors depending on the pH. A precipitate is formed: A chemical reaction has occurred if two liquids are poured together and a solid (called a

The solution can be an acidic‚ base or neutral ranging from 0 to 14.

The experiment also has the student determining what the buffer solution is in an aqueous solution. The student will also be testing the pH of milk of magnesia and will see how it affects the stomach acid. Lastly

Fermentation Fermentation is a natural process that has been going on in nature since before humans existed. For centuries we have been practicing food fermentation‚ knowingly or unknowingly. Every food culture in the world throughout history has been using fermentation in their food in some way. Bread making originated in Egypt 3500 years ago. Fermented drinks were being produced and consumed in Babylon(now Iraq) 7000 years ago. China is thought to be the birth place of fermented vegetables. A
