A substances “utilized in the neutralization process to add acid or alkali to a solution to adjust its pH, guaranteeing complete neutralization for industrial or environmental purposes.”
An aqueous solution’s acidity or basicity (alkalinity) is measured using the pH scale, which ranges from 0 to 14. While pH values below 7 are acidic and those above 7 are basic, a pH of 7 is neutral. Each full pH value corresponds to a tenfold change in acidity or basicity because the scale is logarithmic.
