The reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) is a classic example of an acid-base neutralization reaction, resulting in the formation of salt and water. Understanding the ...

In simple terms, pH is a measure of how acidic or alkaline (basic) a solution is. A pH below 7 indicates an acid solution A pH above 7 indicates an alkaline (basic) solution pH 7 is considered neutral ...

The pH scale measures the acidity or alkalinity of a substance, ranging from 0 to 14, with values below 7 representing acidity, above 7 representing alkalinity, and 7 representing neutrality.
