medulla oblongata as well as airway obstruction may cause respiratory acidosis. 3. Explain how the renal system would compensate for respiratory acidosis. The kidneys regulate the amount of H+ ions and HCO 3- excreted in the urine which regulate acid base balance. A C T I V I T Y 3 Renal Responses to Respiratory Acidosis and Respiratory Alkalosis 1. Describe what happened to the concentration of ions in the urine when the PCO2 was lowered. How well did the results compare with your prediction

Acetic acid‚ a pungent smelling colourless liquid having sour taste‚ used very commonly in the chemistry laboratories. It got its name from Latin word Acetum‚ which means vinegar. Pure acetic acid is also called glacial acetic acid‚ because in winters it freezes easily as temperature goes below 16-17°C. Therefore it looks like as if a small glacier is there in the bottle‚ hence called glacial acetic acid. Laboratory and daily life uses of acetic acid are: (i) Acetic acid is used in household kitchens

INTRODUCTION Lactic Acid is an organic compound with the formula CH3CH (OH) COOH. Lactic is one of the types of fermentation which occur under anaerobic respiration to produce ATP without the use of oxygen. Anaerobic respiration takes place in certain prokaryotic organisms that have an Electron Transport Chain (ETC) but do not use oxygen as a final electron acceptor at the end of the chain (Campbell et all‚ 2015) different with the aerobic respiration which use oxygen to produce ATP and its final

Carboxylic acids are compounds which contain a carboxyl group‚ -COOH group‚ where the -COOH group is attached either to a hydrogen atom or to an alkyl group. One of the example of carboxylic acid is benzoic acid( benzene carboxylic acid) which has a benzene connected to the carboxyl carboxyl group‚ -COOH group. It has a formula of C6H5COOH. The carbon atom of a carboxyl group has a high oxidation state. Therefore‚ that many of the chemical reactions used for their preparation are oxidations. In

Lloyd Term 2‚ 2014 Lauric Acid Experiment Teacher: Mr Oliver Contents 1.0 Introduction Elements and the compounds can exist in distinctive physical states. Liquid‚ solid‚ gas and plasma. Every element and compound has a distinctive melting and boiling point. When a substance reaches its melting and boiling point it will change phase. For example the molecules in a solid being heated gain energy and eventually are able to not only vibrate but

The type of acid was clearly controlled in the method. It clearly states that hydrochloric acid is representing the digestive chemical whilst the antacid tablets represent the food being digested. It is evident that the hydrochloric acid was the acid used in all aspects of this experiment successfully controlling this variable. It is not certain whether the amount of acid was controlled throughout the experiment. This is because the amount of acid was not clearly outlined neither

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance
