    been existing knowledge that crossbreeding plants and animals could enable the desired characteristics to be passed on. However‚ it was his groundbreaking discoveries he made via pea plant experiments conducted by him over 1856 to 1863 that showed how certain traits are passed on to next generation. Over this time period he is said to have tested over 5000 pea plants and from this he derived the law of Mendelian Inheritance He was able to predict the probabilities of certain characteristics being

    Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l)  H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

    Recrystallization of Benzoic acid Chemistry 204-002 Date: 4/9/2011 Hector Ortega Recrystallization is a method used to purify compounds‚ and this is a very important procedure because compounds are naturally impure. Polarity and solubility play a big role in this experiment and these characteristics are exploited in order to have a crystallization of the desired compound. In this experimented benzoic acid was crystallize using ethanol and water. I chose these solvents based on part C of the experiment

    will show a colour change. After that record the initial reading of the burette and making sure that all your burette readings must be to an appropriate precision. Titrate the contents of the conical flask by adding to it 0.100 mole dm3 hydrochloric acid from the burette. Add the solution slowly. Swire the flask gently to mix the contents at the end indicator turns as define red colour. This is the end point of the titration. Record the final burette reading in your table of result. Repeat the titration

    to practice common organic laboratory techniques inside the lab to get one oriented to the basic methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form‚ consisting of benzoic acid‚ methyl orange‚ a common acid/base indicator‚ and cellulose‚ a natural polymer of glucose (Huston‚ and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating

    Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed
