  • Analysis Of Ka And Pkb

    pKa AND pKb USING ACID-BASE TITRATIONS Introduction Acid-base titrations can be used to determine pKa of a weak acid and pKb of a base. A weak acid and a weak base incompletely dissociate in water. For this reason, the concentration of hydrogen ions (H+) and hydroxide ions (OH-) depend on equilibrium coefficients of acid (Ka) and base (Kb). Equation 1 shows the chemical dissociation equation of a weak acid. Furthermore, Equation 2 describes the equilibrium constant of a weak acid. On the other…

  • Argumentative Essay On Alkaline Water

    substance is on a scale of 0-14. For example, if something will have a pH level of 1, it will be very acidic. On the other hand, if it has a pH of 13, than it will be very alkaline. Several experts believe that this type of water can neutralize the acid in your body, because its pH level is higher than regular drinking water. For example,…

  • Phenol Degradation Lab Report

    These organic acids include oxalic acids, maleic acids, muconic acids and so on[18, 20, 21]. Because of the selective nature of ozone with regard to formed by-products, whereby acidic conditions produce a low TOC removal rate, direct ozonation rarely yields complete mineralization. [22]. Alternatively…

  • Multip Ph Lab Report

    seven liquids are considered acid. However, seven is considered a neutral, like distilled water. Therefore, eight to fourteen the liquids are considered basic. For instance, a pH of two is going to be an acidic liquid. Thus, a pH of twelve would be measured as a basic liquid. Additionally, a strip of litmus paper will demonstrate that a solution contains an acid. However, if the solution contains a base the paper will turn blue, and if it turns red the solution is an acid. Also, like the litmus…

  • Sodium Hydroxide Lab Report

    (NaOH) Introduction Acids are anions that have at least one hydrogen cation tacked onto their molecular formulas. The Bronsted definition of an acid states that acid is a proton, H+, donor.3 Acids can fall into one of two categories: they can be strong or weak. Strong acids completely dissociate their H+ and weak acids only partially dissociate their H+.3 This means that a strong acid cannot return to its initial state once it undergoes a reaction. On the other hand, a weak acid can return to…

  • Titration Lab

    added to separate test tubes filled with 5mL of unknown #2. The colour change was observed and compared with the tubes with the acetic acid and its chloro- derivatives with the separate indicators. The identity of the unknown acid was recorded. Then, the pH meter was calibrated with 3 standardized buffer solutions at pH 4, pH 7, and pH 10. Then, 25mL of the unknown acid was added to a 100ml beaker and placed under the burette. The magnetic stirring bar was added and the pH meter’s bulb was…

  • Ch3cooh Reaction Lab Report

    is a strong oxidizing agent, therefore, H2SO4 needs to be added. If permanganate solution changes colour from pink to colourless, then oxalic acid is present in the food. 2KMnO4 + 3H2SO4¬  K2SO4 + 2MnSO4 + 3H2¬O + 5[O] H2C2O4 . 2H2¬O + [O]  2CO2 + 3H2O Overall reaction: 2KMnO4 + 3H2SO4 + 5H2C2O4 . 2H2O  K2SO4 + 2MnSO4 + 18H2O +10CO2 B2. Oxalic acid and oxalate salts are found in many different foods. Why is it important to moderately consume foods that are particularly high in…

  • Analysis Of Rf Value Of Caffeine

    In step d) 10cm3 of dilute hydrochloric acid is added to the separating funnel containing paracetamol, caffeine and ethyl acetate mixture. This protonates the caffeine which therefore gives it a positive charge allowing it to be soluble in the hydrochloric acid aqueous layer whereas the paracetamol stays in the ethyl acetate, since the two mixtures, ethyl acetate and hydrochloric acid do not mix then the caffeine is separated from the paracetamol and ethyl acetate…

  • Broiler Chickenss: A Case Study

    this paper was model the amino acid intake of broiler chickens for optimum economic in different scenarios with MC how to example. The second objective was described in software R the scripts for modeling the optimum amino acid intake for broiler. In addition, we considered the price of whole birds and DL-methionine cost according to Economic scenario. The dilution technique was used to allow formulates the experimental diets with the same balance of amino acids for all treatments (Gous and…

  • Fitness Components Of Squash

    ball warm and bouncy. The type of ball used is determined by the player’s skill level. Squash mainly uses fitness components that include, agility, anaerobic capacity and muscular power. The dominant energy system that squash players use is the Lactic Acid System. The fitness component Agility is the ability of the body to remain balanced whilst changing direction. It is vital for squash players to be agile. Agility is used in squash when the player changes direction constantly to get close…
