If you don't know the concentrations of your initial solutions, calculate molarity by dividing the number of moles in a solute by the volume of the solution in liters. For example, the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this...
The pH level of a solution is a measure of its hydrogen ion concentration. Solutions with a high concentration of hydrogen ions have a low pH, and solutions with a low concentrations of H+ ions have a high pH. A simple working definition of pH is pH = - log[H+], where [H+] is ...
To calculate the pH of a buffer solution, the Henderson-Hasselbalch equation is used, pH = pka + log(acid/base). If working with a weak acid and conjugate base, the pka is found and plugged into the concentrations for each added to the solution.What...
Concentrations of solutions Periodic table with valences TL;DR (Too Long; Didn't Read) A basic background in chemistry is useful in determining molar concentration and valences. You can use an ionic strength calculator to find ionic strength of a solution, which minimizes math errors. Select ...
Explain the effect on the concentration of a solution if it is "over-boiled." How to calculate the concentration on a Beer's law plot? In fluorescence, why do we have to prepare a calibration curve for every compound in our sample?

Example Problem 1 - Calculating the pH of a Strong Acid-Strong Base Solution 350 ml of a 0.02 molar solution of NaOH is added to 500 ml of a 0.03 molar solution of HCl. Calculate the pH for the final solution. Step 1:Identify the acid and base in the solution. Acid-HCL, B...
We can report solution concentrations qualitatively by describing a solution as dilute or concentrated. A quantitative way to express the concentration of a solution is by using concentration units. One example of a concentration unit is mass per volume percent. It typically has the units of grams...
AUC calculations are simple but nuanced. In this blog, we look at how to calculate AUC with non-compartmental analysis techniques.
Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
