We found that students using MBL exhibited a larger positive shift in their concept map scores, which indicates a greater differentiation and integration of their knowledge of acids and bases. The chemical indicator students exhibited a more moderate positive shift in their concept map scores, and ...
Acid Base pH is the ultimate tool for accurate estimation of pH values of acid – base aqueous systems. This application calculates pH values of solutions of weak and strong, monoprotic and polyprotic acids and bases and additionally builds titration curves and provides pH and titrant volume valu...

bases. While the pH scale is the most widely recognized and frequently used, there are other important measurements such as pKa, Ka, pKb, and Kb. Each of these offers insight into the behaviors and properties of acids and bases, and they are crucial in helping to understand acid-base ...
Any of a class of water-soluble compounds, having sour taste, that turn blue litmus red, and react with some metals to liberate hydrogen, and with bases to form salts. Any compound that easily donates protons; a Brønsted acid lysergic acid diethylamide (LSD) ...
