The solution is acidic if its pH is less than 7. If the pH is higher, the solution is basic (also referred to as alkaline). Solutions with a pH that is equal to 7 are neutral. Apart from the mathematical way of determining pH, you can also use pH indicators. The most universally ...
The fluorescent pH indicators used to detect acidic organelles and to follow trafficking through acidic organelles must have a lower pKa than those described in Probes Useful at Near-Neutral pH—Section 20.2. Also, unlike most pH indicators for cytosolic measurements, pH indicators f...

A pH of 7 is neutral, a pH less than 7 is acidic, and a pH more than 7 is basic. How do you calculate the pH of a buffer solution? 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...

The hydroxyl groups may have acid (pKa = 2.9) or basic character (pKa = 12.7), if they are bidentate or monodentate, respectively (Herrmann and Boehm, 1969). For these reasons the TiO2 surface can be protonated or deprotonated depending on the pH value of the aqueous suspension (Fig. 1.12...
What is true about a solution whose pH is less than 7? What is the pH of 0.1 mol L-1 HCl? What is the approximate pH of a solution of 1.00M CH3COOH? What is the pH of a 0.05 M Na_{2}HPO_{4} solution? The molar concentration of H+ ions in a solution is 5.8 x 10-9. ...
PHTHALAMIDE is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react wit...
