Mediterranean countries around 2500 years ago. The basic process has not changed much although now the chemistry is understood. Soap is made from the process called saponification‚ the alkaline hydrolysis of fats and oils. It is essentially the reverse of esterification. O O R-C-O-R’ + NaOH ---- R-C-O-Na+ + R’OH Ester(fat) + base(caustic soda) ---- salt of fatty acid(soap) + alcohol(glycerol)

PhysioEx 9.0 Exercise 3 Neurophysiology of Nerve Impulses A C T I V I T Y 1 The Resting Membrane Potential 1. Explain why increasing extracellular K_ reduces the net diffusion of K_ out of the neuron through the K_ leak channels. Increasing the extracellular potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

5 to 6.0. Yet when in the presence of sodium acetate blue litmus stayed blue whereas red litmus turned blue‚ indicating its basicity. pH probe also showed the solution’s pH varied between the line of 10 to 14. Calcium chloride was also observed to be acidic. The only conflicting result was sodium chloride‚ which in the presence neither of the paper changed color‚ but was determined to be acidic according to the probe. However‚ their pH
