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 ...
Explain how solutions are classified as acids or bases. Then, provide an example of a weak acid. Solution: Any homogenous mixture of two or more substances, usually classified as solutes and solvents, is known as a solution. A solution is generally divided into th...
Red cabbage indicatoris a simple way to tell whether a substance is anacidoralkali. Acidscan be found in the food we eat, in our bodies and around the home. Some acids, especially those found in cleaning products, can be very harmful, so take care when using them and always read their...
Explain the difference between acids and bases. Given an example of both. Identify the acid-base reaction. CaCO(s) + SiO2(s) to(heat) CaSiO3(s) Tell which hydrogen is the most acidic in the given molecule. Identify the weaker and stronger acid and base for: HPO_4^{2-} (aq) +...
(aka the titrant) is added to react with the analyte. Usually, acids and bases are reacted in titrations using an indicator to tell when the pH changes at the equivalence point, the point where enough titrant was added to neutralize the analyte. At this point, the number of...
There is no tRNA corresponding to the stop codons. The amino acid sequence specified by this small mRNA is methionine. We know this sequence of amino acids by using a table of the genetic code. The genetic code table above is for mRNA and specifies the bases in the first, second and thi...
Photo: Some acids, such as lemon juice, are perfectly safe to handle; others will burn your skin and can do painful, permanent damage. How can you tell which is which? Simply, by measuring pH.If you're interested in measuring acidity, it helps if you know what it is before you start...

Now, we’re going to get to what’s a bit different about your work in just a second, but first let’s talk about the enzyme that your work actually involved, OGG1, can you tell me why this enzyme is of interest in the first place? Maurice Michel Yes, so OGG1 is a DNA repair...
“Certain acids, such as exfoliating acids, can also impact the skin’s pH.” So while all of those exfoliating products provide benefits for the skin, it is important to avoid over-exfoliating and remember to moisturize the skin. Exfoliate once or twice a week to ensure that you’re not...
