Explanation:

Influence of Solution pHs

Changing the pH of a solution is likely to influence concentrations of reactive species inside reaction systems using certain AO/RPs, thereby affecting the efficiency of the processes [23]. Consequently, some common trends could be predicted about the efficiency of various AO/RPs regarding the changes in solutions pHs. For instance, the Fenton processes have the maximum efficiency at low pH (i.e., pH < 3) [40]. However, the efficiency of the Fenton reactions is badly reduced at alkaline pH, attributed to the precipitation of iron catalysts [40]. The point of zero charge (PZC) is an important parameter affecting the efficiency of photocatalysts, and it in turn, depends on the pH [67]. For instance, the surface of TiO2 particle will be positively charged at pH < pHpzc, negatively charged at pH > pHpzc, and neutral at pH = pHpzc. These characteristics remarkably affect the adsorption-desorption properties of TiO2 toward the reactants or reaction intermediates, consequently affecting the degradation efficiency [127]. The higher concentration of HO− at alkaline pH may increase the concentration of •OH [reaction (6.4)], which may subsequently increase the removal efficiency of the pollutant [127]. The efficiency of the radiolytic reduction processes, being predominantly controlled by eaq−, was generally reduced at acidic pH, attributed to fast scavenging of eaq− by H+ [37, 112]. The efficiency of UV/sulfite process was high at pH above 7.2 (i.e., pKa), since sulfite ion (SO32 −) dominated the total sulfite species at this pH range, which can effectively absorb light to generate SO3•− and eaq−, to be used in the degradation processes [128].

Answer 2

Answer:

HERE IS A SIMPLE  EXAMPLE!

Explanation:

LET THE VALUE OF HCL [ HYDROCHLORIC ACID] - 3.0

LET THE VALUE OF  NaOH [ SODIUM HRDROXIDE]- 14.0

HERE THE BASE IS STONG AS T IT IS AT MAXIMUM AND POWERFUL THAN THE ACID.

IT REACTS WITH HCL AND HEAT EVOLVES WITH H20 VAPOURS!
