The scientific principle behind this experiment is based on the interaction between the acid-base indicator and the hydrogen ions (H+) or hydroxide ions (OH-) in the solution. Acidic solutions have a high concentration of hydrogen ions, while basic solutions have a high concentration of hydroxide...

The objectives were to evaluate the carbon retention and stability of Ca(OH) 2 -modified biochars and assess their impact on soil greenhouse gas emissions in acidic red soil. Results show that Ca(OH) 2 modification significantly enhances both carbon retention and stability in biochars. Among the...
This magmatic activity has developed in subsidence-related areas such as ISB and resulted in the formation of alternating basic (i.e. trachyandesites or trachybasalts) and acidic (porphyries and rhyolites) rocks. Meanwhile, clastic and chemical sediments (i.e. shales, sandstones, and limestone...
(iron meteorites contain 0.02 percent). Calcium predominates in the lower part of the earth’s crust, accumulating in basic rocks. A large amount of calcium is found in the feldspar anorthite, Ca[Al2Si2O8]; basic rocks contain 6.72 percent and acidic rocks, such as granites, contain 1.58 ...
It is also used in fresh water treatment for raising the pH of the water so that pipes will not corrode where the base water is acidic, because it is self-regulating and does not raise the pH too much. It is also used in the preparation of ammonia gas (NH3), usin...

The pH was varied from pH 1 to pH 11 (Table 8) and hypsochromic <1994PAC1088, 1996PAC2230> and bathochromic <1994PAC1124, 1996PAC2247> effects were observed, suggesting that the suitable form of 42 for nucleophilic substitution exists only under acidic conditions (Equation 2). Sign in to...
