Buffer Solution Preparation Using a Balance

Web Reference: Learn how to calculate the required amounts of components to prepare a buffer solution of a specific concentration and pH. Familiarize yourself with the procedures for preparing and adjusting buffer solutions. Learn how to save time and effort preparing accurate buffer solutions with METTLER TOLEDO precision balances and pH meters. Common preparation methods include: 1) dripping an acid (or alkali) into an aqueous solution of a salt while measuring the pH with a pH meter and 2) making an aqueous solution of acid with the same concentration as the salt and mixing while measuring the pH with a pH meter.

YouTube Excerpt: Buffer solution preparation takes time and must be done with care to ensure the buffer performs as desired. When the quality of your products or your biochemical analyses depend on the performance of your buffer solutions, you want to be sure you get them right first time. Preparing buffers consists of several steps: Weighing-in the components, dissolving the components, adjusting the pH and replenishing to the final volume. As the ratio of the acid to base in a buffer is directly related to the final pH, it is vital to weigh the components with a high degree of accuracy. So, it is important that the equipment used (balance, pipettes and pH meter) are properly calibrated and have sufficient accuracy.
