In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). In the intestine the gastric acids are neutralized (pH 7)‚ and pepsin is no longer effective. "Pepsin (biochemistry)." Encyclopedia Britannica Online. Encyclopedia Britannica‚ n.d. Web. 10 Dec. 2012. Research Question: Does changing the pH of pepsin affect the ability to break down the protein (mass of jello). Variables: independent- Ph level dependent- The mass of the jello

Moon-Ho Jung set out to not only help define a “coolie” but also to help us understand that "coolies" towed a line between slavery and freedom. The term "coolie" is quite tentative but the basic idea is that a “coolie” refers quite broadly to people of a subjugated “race” who have emigrated from another country to become cheap labor. Often the term “coolies” are targeting the Chinese‚ but it also expands to immigrants from India and the Caribbean. With the idea of exactly what a “coolie” might be

The effects of pH on mung beans Gloria Cheng Winsy Cheung Lily Wong Christine Yen January 15‚ 1998 Abstract This experiment explores how different pH environments affect the growth of mung beans. The mung beans were grown in water with various pH levels‚ consisted of pH levels 5‚ 6‚ 7‚ 8‚ and 9. A replicated design was used consisting of 3 runs for each pH level. The following results are listed in order of pH levels allowing most growth to least growth of the mung beans: 7‚ 8‚ 6‚ 5‚ and 9. These

for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls varied for each pH buffer
