identify the acidity or alkalinity of solutions using cabbage? II. TITLE The Mercurial Cabbage III. RATIONALE We searched on the internet and came across this piece. It seemed like a cool experiment at a glance but as we read through we found it helpful. We decided to add this on our list of proposals. We were also curious and wanted to know the acidity and alkalinity of certain liquids since this is like an acidity or alkalinity indicator. This study can help many people‚ the ones that need

Will Godfrey Chemistry Miss. Morrison May 21‚ 2000 Natural Indicators Each year millions of tourists travel to the woods of New England‚ upstate New York‚ Wisconsin‚ and Canada to witness the appearance of brilliant autumn colors. Sugar maples‚ red oaks‚ sumac‚ birch and other trees and shrubs turn from green to bright red‚ orange‚ and yellow. The short‚ cool days of autumn bring an end to the production of chlorophyll (the green light-gathering pigment). As chlorophyll gradually breaks

lab is to determine the pH level of common household products. Introduction Liquids are either acidic‚ basic‚ or neutral. We are able to figure out which one it is based on properties‚ along with the pH. Acids taste sour‚ and bases taste bitter. Using the pH scale‚ you are able to know how strong of an acid or base a liquid is. High concentration of [H+] ions means that the liquid has a low pH. Therefore a liquid with a low concentration of [H+] would have a high pH. A pH of less than 7 represents

In the cooler areas of the country‚ where frost usually occurs early or late in the season‚ Glory of Enkhuizen‚ Kiaps Spits‚ Green Coronet and Gloria can be planted from January to March‚ and Green Star and Bonanza‚ from August to January. In the warmer areas of the country‚ where little to no frost occurs‚ Glory of Enkhuizen‚ Kiaps Spits‚ Green Coronet and Gloria can be planted

Datalogging Experiment (4) Acid-base Titration using Method of Double Indicators Student Handout Purposes To determine the composition of the following mixture by double indicator method: 1. NaOH(aq) and Na2CO3(aq) 2. NaHCO3(aq) and Na2CO3(aq) Introduction Consider a mixture of NaOH(aq) and Na2CO3(aq). Reaction between HCl(aq) and Na2CO3(aq) takes place in two stages: HCl(aq) + Na2CO3(aq) ⎯→ NaHCO3(aq) + H2O(l) …………………. (1) HCl(aq) + NaHCO3(aq) ⎯→ NaCl(aq) + CO2(g) + H2O(l) …………. (2) While

Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips * 20 test tubes

Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best results when testing the pH within a solution. The pH‚ which stands for the proportion of hydrogen ions in a solution‚ could be acidic (acidosis)‚ neutral or basic (alkaline). The pH scale goes from numbers 1 through 14. A pH of 7 is neutral; meaning the amount of hydrogen
