Joshua McMahon IB Chemistry Matt Chase 3A 2/13/15 Finding the PH of different concentrations of orange juice. Research Question By diluting concentrated orange juice with water‚ can you significantly change the PH value? Introduction Across the world‚ it is thought and widely accepted to believe that Orange juice is the cure to many terrible diseases. However‚ this may not be true anymore. It has been said that Oranges are very high in vitamin C‚ therefore one should drink it every morning

The Case of pegging the Exchange Rate of Oil-Exporting Economies to the Dollar High oil prices are again transforming oil-exporting economies. Economies that were declining when oil hovered in the $20s for most of the 1990s—and at risk of bankruptcy when oil dipped to $10 a barrel in 1998—are now booming. A new generation of skyscrapers is rising in the Gulf‚ in St. Petersburg‚ and in Moscow. Government reserves in oil-exporting economies are overflowing with the governments’ large cut from the

Red Cabbage Indicator Indicators are chemical compounds that can be added to a solution to determine whether it is acidicor alkaline. The indicator will change colour depending on whether an acid or an alkali is added. The colour in red cabbage (it is a pigment called an anthocyanin) makes a very good indicator. Acids and alkalis Acids have a sour taste‚ like vinegar (which contains ethanoic acid) and lemons (which contain citric acid). Alkalis are substances that react with acids and neutralise

I. PROBLEM How to 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

The Cabbage Indicator Experiment My hypothesis for this experiment is if I put an acid or a base in to a neutral then it will change colors. My hypothesis was correct in assuming that it would change colors with different substances or mixtures. If I put an acid or a base in to a neutral then it will change colors. The red cabbage indicator did change colors. Greens for bases and reds and pinks for acids. An alternative hypothesis for this could be “If the red cabbage indicator is purple then adding

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
