    (Fe3+ ) form. Ferric form is not usually absorbed in the body. In the stomach‚ there is low pH of 2 due to presence of gastric acids such as Hydrochloric and Ascorbic acids. These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid ‚ the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+

    ____________________________________________________________ ____________________________________________________________ ______ This lab was basically about finding the percentage of acetylsalicylic acid in an aspirin tablet. First‚ the base was created‚ which was made out of 1.00 g of NaOH and D-water. Then the buret was attached to the clamp on the ring stand and the base was poured into the buret. After that‚ one by one‚ an aspirin tablet was dropped into an Erlenmeyer flask filled with 50 mL of D-water

    Bases are substances that are in aqueous solution‚ are slippery to the touch‚ taste bitter‚ change the color of indicators Examples turn red litmus paper blue and react with acids to form salts‚ promote certain chemical reactions. General properties of a base are Concentrated or strong bases and are caustic on organic matter and react violently with acidic substances. Also bases can are bitter in taste. And the pH of a basic solution at standard conditions is greater than seven. Strong bases are

    Acids and Bases are two groups of chemical compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are

    hours. In the petri dish labeled tap water‚ 10 out of 10 seeds sprouted into plant growth as seen in Figure 5.1. The radish plant growth within the tap water petri dish grew so well it started to lift the lid off the dish. The results from the Acid Rain (50% vinegar solution) did not allow any radish seeds to germinate. There were never signs of seed germination while observing the seeds over a three week period. In the petri dish labeled Acid Rain‚ 0 out of 10 seeds sprouted into plant growth as seen

    concept of a conjugate acid-base pair. Using equilibrium law and K‚ explain the relationship between the strength of an acid/base and its conjugate. Conjugate Acid-Base Pair: Conjugate acids and bases were presented by Bronsted-Lowry‚ who was a chemist who proposed the theory that both acids and bases required the transfer of a proton in order for there to be a reaction. An acid will donate a proton (proton donor)‚ forming what is considered to be a conjugate base. When the base accepts a proton (proton

    Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding
