New York, United States – December 24, 2019 /MarketersMedia/ —

On December 22, 2019, Alfa Chemistry announced that several web tools on its website are available to assist customers in the scientific research field.

This US company has served the pharmaceutical and biotechnology industries for more than a decade. Alfa Chemistry offers an extensive catalog of organic building blocks, reagents, catalysts, reference materials and research chemicals. In addition to chemical products, it also provides customers with analytical services and laboratory services. The 4 newly launched web tools on its website provide assistance to customers in the scientific research field. The description and usage of these 4 web tools are as follows:

pH Calculator
H+ concentration is often used to indicate the acidity and alkalinity of the solution. When [H+] is less than 1mol·L-1, the acidity of the solution (pH) is usually expressed by the negative logarithm of the hydrogen ion concentration (-lg [H+]), that is, pH = -lg [H+], which is also the equation used by pH Calculator. For example, since hydrochloric acid is a strong electrolyte, it is completely ionized in water. When calculating the pH of a 0.01mol·L-1 hydrochloric acid solution, since [H+] = 0.01mol·L-1, so the pH of this solution is: -lg [H+] =-lg(0.01)= 2. However, the use of concentration units is sometimes inconvenient because the concentration of the reactants can vary by many orders of magnitude. When dealing with concentrations that span multiple orders of magnitude, the concentration is often expressed as a p-function. The p function of the number X is written as pX and defined as pX = -lg (X). Therefore, the pH value of a solution with H+ concentration of 0.10 mol / L: pH =–lg [H+] =–lg (0.10) = 1.00. The pH value of the solution with H+ concentration of 5.0×10-13 mol/L can be calculated by: pH =–lg [H+] =–lg (5.0×10-13) = 12.30.

Mass Molarity Calculator
When a suitable volume of pure solid or pure liquid is weighed and diluted to a known volume to prepare a solution, how it is done depends on the required concentration unit. For example, to prepare a solution with the required molar concentration, it is necessary to weigh out a reagent with appropriate mass, dissolve it in a portion of the solvent, and then adjust to the required volume. To prepare a solution with a given solute concentration, it is necessary to measure an appropriate volume of solute and add enough solvent to obtain the desired total volume. Mass, molar concentration, volume, and formula weight are related to each other and their relationship can be expressed by the formula: mass (g) = concentration (mol/L) * volume (L) * formula weight (g/mol). The Mass Molarity Calculator uses this formula to calculate the mass of the solvent to be added. For example, if we need to use solid NaOH to prepare 500 mL of NaOH liquid with a concentration of 0.20 mol/L. The required mass of NaOH is = 0.2 mol/L * 0.5 L * 40 g/mol = 4 g.

Solution Dilution Calculator
Low-concentration solutions are usually prepared by diluting higher-concentration stock solutions. Since the total amount of solute before and after dilution is the same, the principle used by the solution dilution calculator, that is, the formula, can be expressed as Co * Vo = Cd * Vd. Among them, Co is the concentration of the stock solution, Vo is the volume of the stock solution to be diluted, Cd is the concentration of the dilute solution, and Vd is the volume of the dilute solution. For example, using a stock solution of NH3 with a concentration of 14.8 mol/L to prepare 250 mL of a solution of NH3 with a concentration of about 0.10 mol/L, the relationship between their concentration and volume can be expressed by the equation: 14.8 mol/L * Vo = 0.10 mol/L * 0.25 L, so the value of Vo can be calculated by: Vo= 0.10 mol/L * 0.25L / 14.8 mol/L=1.69 * 10 -3 L or 1.69 mL.

Unit Converter
Unit converter is used for simple conversion of volume and mass units. For example, you can try to convert 3 g = x kg, enter 3 in the blank below “I want to convert”, choose the known unit “Gram (g)”, and you will get X = 0.003.

In addition, Molecule Weight Calculator is still under construction and is expected to be online soon. For more information, please visit the Web Tools page: https://www.alfa-chemistry.com/resources/web-tool.htm.
