Many Physic Principles Well Illustrated By These Experiment Designs.

A very scientific design using physic principles to illustrate potential energy, kinetic energy, lever system,electronic gadzet and etc--to produce work output. it may seem a bit absurd ,might be using a bit camera trick to cover up the effiency of the machine system. Nevertheless it is very excellent and unique, seemingly real and workable by established principles in physicsDont' miss. Check-In ==>XXXXX . Remember to come back here to the blog.

pH and pH indicators; Acid/Base and Titration



here is alkali metals as they react with water.. for real! not fake :) If you like Cesium like I do, I have some interesting pictures on my wiki page you might like: http://en.wikipedia.org/wiki/User:Dnn87
Dont try it on your own –DANGEROUS!!

We are looking at the following acid-base indicators: methyl orange, methyl red, bromothymol blue, litmus, phenolphthalein and indigo carmine. Consider that these indicators all have their effective pH range at which they turn colours.dupuis.shawbiz.caUniversal indicator is a mixture of several indicators displaying a variety of colors over a wide pH range so it can be used to determine an approximate pH of the solution.Titration kits can help to mix lye in with the oil when making biodiesel; learn more from our biodiesel expert in this free alternative-fuel use video.

This was a final project for a Chem Honors Class
