Bonds polarity A water molecule consists of two atoms of hydrogen covalently bonded to one atom of oxygen. The oxygen atom is more electronegative than the hydrogen atom and thus the electrons are not equally shared in the bonds. The electrons in the bonds within the water molecule spend slightly more time around the oxygen […]

pH stands for "potential hydrogen" or "power of hydrogen". On a simple level, the pH scale can be viewed as a ranking of hydrogen ions in a solution. The more hydrogen ions → the lower the pH number → the more acidic the solution.  We could write the scale using the number of hydrogen ions (eg. 1 […]

Setting Up Galvanic Cells A galvanic cell converts chemical energy into electrical energy by a process called redox reaction. Two metal strips are set up as electrodes immersed in salt solutions and are connected by a wire to allow electric current to flow.   The picture below shows a typical setup for galvanic cells. The […]

Significant Figures There's a moral to the story; it's about false precision! It occurs when data is presented in a manner that gives the appearance of more precision than is justified. The tour guide had wrongly assumed that the date of the rock given to him was precise to the year. For many students, significant […]

Hello! A few students have written to ask why carbon to carbon bonds just don't fulfill the octet rule? Here's a quick explanation to help you connect the dots. Two carbon atoms can form single, double or triple bonds to share their electrons. The picture above shows two carbon atoms sharing an electron each to […]
