Running Head: Factors Affecting Citric Acid Production by Aspergillus niger Factors Affecting Citric Acid Production by Aspergillus niger Ong Chia Swing‚ Student. Nilai University 1. Introduction Citric acid is a natural preservative or conservative that is used to add an acidic‚ sour taste to foods and beverages. In the context of biochemistry‚ the conjugate base of citric acid which is the citrate plays an important role as an intermediate in the citric acid cycle which occurs in the metabolism

Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

Weak Acid Titration Abstract: Our method for determining the unknown weak acid was to determine the equilibrium constant K from the molecular weight of the weak acid from our titration data. In this lab the acid Potassium hydrogen phthalate and two unknown acids were titrated. We determined the molar mass of the Potassium hydrogen phthalate‚ for the unknown acids we calculated the molar mass and the Ka values. We used NaOH as the known base for titrating in all three of the titrations. Our

air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before they enter the recycling process. They should only be drained to a purpose built effluent treatment plant so that the acid can be treated and neutralized. Next the batteries are broken in a hammer mill

and bought on a huge scale. Africa has seen four great phases of slave trades. The trans-Saharan‚ Red Sea and Indian Ocean slave trades are oldest slave trades which the continent experienced during 800 AD. In these slave trades‚ Africans were carried from the southern Saharan desert‚ internal of the Red Sea‚ and internal of the coast of Eastern Africa‚ and were transported to Northern Africa and the Middle East. Trans-Atlantic Slave trade is the most researched and a largest slave trade of all during
