Discuss how buffers help to regulate body pH. The pH level in the blood is maintained by the kidneys and the lungs. The pH level on the blood should be at 7.4. In order for the kidneys and lungs to maintain this pH level it affects the buffers in the blood. The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize it so the body is not overly acidic or basic. When these buffers attach to the

Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

Science Research Paper Have you ever wondered how much sugar it takes to overflow a mug in different water temperatures. I thought it would be cool to find out so i did an experiment. I used five diffferent temperatures of water 1.) cold tap water 2.) refrigirater water 3.)freezer water 4.) hot tap water and 5.) boiling water. I filled up a 2 cup mug with 1 3/4 cups of each type of water and added sugar until the mug overflowed. Purpose: I chose this experiment because I thought it would

dissociation constants of weak monoprotic acids were determined with the aid of a buffer and pH meter. Experiment: This experiment was performed according to the procedures as provided in the Chemistry 111B laboratory manual: Po‚ Henry and Senozan‚ N. "General Chemistry Experiments Chemistry 111B"‚ 8th Ed.‚ 2004 Hayden-McNeil Publishing‚ pp 80-88. To determine the dissociation constants of weak monoprotic acids (HX and HY)‚ a buffer was needed to calibrate the pH meter. According to the manual‚ all four solutions

The various types of malware are viruses‚ worms‚ Trojan horses‚ polymorphic threats‚ virus and worm hoaxes‚ back door or trap door‚ denialofservice and distributed denialofservice‚ and mail bomb. b. A virus must be executed such as opening an infected email attachment while a worm can be initiated with or without the user downloading or executing the

the address of function call instruction is saved in stack as a return for the function. When the function executes‚ it allocates local variables‚ including buffers to stack and they are given a lower address than the return address. So‚ in this scenario the return address is a certain level above the base address for buffers and if the buffer is overflowing‚ then it is most likely that an attacker can change return address as well. If the return address is changed to some random value‚ then it will

INTRODUCTION INTRODUCTION TO INTELLECT SPEED BREAKER USING CAN PROTOCOL This project deals with limiting the speed of the vehicle by employing technology of embedded systems using “Peripheral Interface Controller (PIC 16F877A)”‚ when the vehicle enters the speed limiting zone. The parameter to be controlled in this project is speed. PIC has the advantage of enhanced FLASH memory with the modified Harvard architecture and having simple 35 instructions.
