DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

Acid Rain Definition: The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852‚ when the English chemist Robert Agnus invented the term. From then until now‚ acid rain has been an issue of intense debate among scientists and policy makers. Acid rain‚ one of the most important environmental problems of all‚ cannot be seen. The invisible gases that cause acid

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to

Melissa Carrithers AP Chemistry period 6 2-11-15 Determination of Ka of Weak Acids Purpose: The purpose of this lab is to find the strength of weak acids by determining the equilibrium constants for their ionization reactions in water. Is to use their measured pH values to calculate the pKa for the two unknown weak acids thus determining their identities. Hypothesis: If we neutralize a solution that contains a weak acid by adding a strong base to the solution‚ then the ions will be isolated and

endothermic reaction happened everywhere around us. Basically exothermic and endothermic reaction is transfer energy to the surroundings and take in energy from the surroundings (BBC GCSE bitesize). If the reaction forward ，then is exothermic.If the reaction is the backwards ‚then is endothermic. When a reaction take place‚ the energy started to transfer from different object to the surroundings or take away energy from the surroundings. When temperature started to change.

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
