The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work wi
Explain how to find which compound will be a stronger acid or a stronger base. Basicity The less the electronegative element, the less stable the lone pair will be and therefore the higher will be basicity. Basicity decreases as we go down the column. ...

Acids are substances that contribute molecules, while bases are substances that can accept them. Learn how to define acids and bases, explore the pH scale, and discover how to find pH values. Related to this QuestionExplain the difference between an acid and a base. Compare and desc...
Biomedical Scientist:Biomedical Scientist work to gain knowledge on the main principles of how the human body works and reacts to various drugs. By continuously testing and researching, biomedical scientists often find ways to prevent or fight a disease. Many times, they are the frontrunners when...
Acids, Bases and Equivalents For acids an equivalent is the number of hydrogen ions a molecule transfers. In acids it is straightforward to find equivalent units. Look at the number directly after the hydrogen, H, in the chemical formulas below. The number provides the number of equivalents ...
Steps to Find the Predominant Form of an Acid or Base Step 1:Read the question carefully and determine what is being asked. Step 2:Use the Henderson-Hasselbalch equation to calculate the relative quantities of the acid and conjugate base. ...
We discuss the 1-dimensional 'sliding' motion of protein along non-specific DNA, often proposed to be the mechanism of this multiple site sampling, and we discuss the role of short-range diffusive 'hopping' motions. We then derive the optimal range of sliding for a few physical situations, ...

I wanted to find out a little more about how the winner was chosen and how Maurice was picked out from all the entrants, and so, before the ceremony at the European Molecular Biology Laboratory, I called up one of the judges Reinhard Jahn the retired director of the Max Planck Institute ...
