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
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...
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 and Bases from Chapter 2 / Lesson 10 111K 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...
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. ...
The principle of solubility, "like dissolves like," emphasizes the importance of polarity in determining whether substances will mix. Polar molecules, such as water and ethanol, dissolve in each other due to their similar net dipoles. Understanding the polarity of various organic compounds,...
To calculate the pH of a buffer solution when base is added, the Henderson-Hasselbalch equation, pH = pKa + log (acid/base), is used. The mol of base is added to the buffer's base, and the base's mol is subtracted from the buffer's acid. These new mols are used to find the ...
This guide introduces restriction enzymes, providing in-depth reference information and tools to help you find buffers for double digests, or find enzymes by name or recognition sequence. Restriction Enzyme Tools are available for desktop or mobile....
You probably have jars, boxes and containers of outdated, surplus and waste chemicals that are lab wastes and should be "lab packed". What is a lab pack? Over time, you will find that jars and cans have accumulated that are out-of-date, contaminated, partially used, leaking, or simply ...
