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
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...

you add chemicals to water, the solution can become either acidic or alkaline. 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...
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?
Otherwise, it shows “The solution is Neutral” in cell E5. Use the Fill Handle tool to extend the formula to other cells. Read More: How to Calculate Logarithmic Growth in Excel Common Errors While Calculating Logarithms in Excel Be aware of these common errors when using the LOG function:...
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...
Calculate the solubility of ferric oxyhydroxide, Fe(OH)_{3} if its solubility product constant {eq}K_{sp} {/eq} is {eq}1.6 \times 10^{-39} {/eq} at room temperature. Step 1:Find the dissociation equation for the compound and identify the ions in the solution. ...
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 ...
