Acids and bases are opposite of each other. Acids are solutions where the pH value is less than 7. Bases have pH values greater than 7. The perfect acid and perfect base will combine to form water, which will have a pH of 7.
The calculation of pH of acids and bases can be obtained on the basis of chemical speciation calculation. The solution's nature decides the level of complicacy demanded to evaluate the pH value.Thus, the pH value of a weak acid with the help of an example is shown below: Example: Calcula...
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...
Can you mix acids and bases? If we mix equal amounts of an acid and a base then two chemicals essentially cancel out each other and produce salt and water. Mixing equal amounts of a strong acid with strong base results in a neutral solution whose pH value remains 7 and this type of ...
Clearly, indicators with acidic transition ranges must be employed for weak bases. From these examples it is obvious that the weaker the protolyte the more difficult it is to determine. The pK value of the titrated protolyte (pKa or pKb) should not be greater than 5–6. Protolytes weaker...
A low pKa valuethat the compound isacidicand will easily give up its proton to abase. 低pKa值化合物为,容易将质子给出到碱。 LASER-wikipedia2 For mixtures containing strongacidsorbasesthe pH should be used as classification criterion (see 3.3.3.1.2) since pH will be a betterindicatorof serio...
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) ...
phenolphthalein- a laxative used in many preparations under various trade names; also used as an acid-base indicator in titrations involving weak acids and strong bases because it is brilliant red at high alkalinity and colorless below pH 8 ...
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 ...
