Fajardo of BSFT 2-1N 1. Calculate the pH of a dilute solution that contains a molar ratio of potassium acetate to acetic acid (pKa=4.76) of: a. 2:1 pH = 4.76 + log[2]/[1] = 4.76 + 0.3010 = 5.06 b. 1:4 pH = 4.76 + log[1]/[4] = 4.76 + (-0.6021) = 4.16 c. 6:5 pH = 4.76 + log[6]/[5] = 4.76 + 0.0792 = 4.81 d. 2:3 pH = 4.76 + log[2]/[3] = 4

Maryely Ramirez Professor Theresa Sterner Bio Lab 105 04 November 2013 The Effects Environmental Temperature and pH have on the Activity of Porcine Pancreatic Amylase Introduction There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions‚ such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva‚ and pancreatic secretions of the small intestine. The function of amylase is

The tests we conducted were: temperature‚ turbidity‚ conductivity‚ flow rate‚ pH‚ and GPS. The location where we conducted the tests was White Rock Creek. It was in between lots of trees and it was on a slope. The biotic factors located in the creek were moss‚ algae‚ trees‚ grass‚ minnows‚ spiders‚ and

The objective of developing a virtual interface that acquires data from physical instrument (pH probe) used in the monitoring of a chemical process (in our case an acid base titration and a saponification reaction). The acquired data is processed offline and analyzed for further calculations. Key Words: -Virtual interface‚ Saponification Reaction‚ pH probe‚ etc. I.

are chemicals that the body releases into the blood stream to help maintain a healthy pH level. Carbon dioxide (CO2) acts as an acid by donating hydrogen ions when needed and forms carbonic acid when it dissolves in water. Carbonic acid bicarbonate is important for maintaining an acid base balance in the blood as it equalizes the pH (7.5) of the blood. All body fluids have buffers that defend the body against pH changes. A process that affects buffers in the blood is exercise. The muscles require

Objective: Learning how to Prepare Buffers of Various pH levels and Preparation of Acetate Buffer. Introduction A buffer is a solution having the capacity to resist changes in pH levels. Mostly a buffer consists of a weak acid and a salt of strong base or a weak base and a conjugate salt of strong acid e.g. acetate buffer is the most common buffer in which equimolar mixture of acetic acid and sodium acetate solution is used. CH3COOH CH3 COO - + H+ CH3COONa CH3COO - + Na+ Buffers are
