SSC MTS EXAM

Detailed explanation-1: -pH is a measure of how acidic/basic water is. The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Detailed explanation-2: -Neutral solution – Neutral solutions are those in which the concentrations of hydrogen and hydroxide ions are the same. A neutral solution could be a sodium chloride solution or a sugar solution. The pH of a neutral solution is 7. Another frequent material that has a pH of neutral is water.

Detailed explanation-3: -Pure water has a neutral pH and some formulations of phosphate-buffered saline also have a neutral pH. Solutions close to a pH of 7.0, like human blood (pH = 7.4), have a near-neutral pH and may be categorized in a neutral pH range.
