Question

How does the pH Scale Measure Acidity?

Answer 1

Hint: The pH scale in chemistry is used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher \[{{H}^{+}}\] ion concentrations) have lower pH values than basic or alkaline solutions.

Complete answer:
The pH scale is logarithmic and indicates the concentration of hydrogen ions in the solution in inverse order. This is due to the pH formula being based on the negative of the base \[10\] logarithm of the molar concentration of hydrogen ions in the solution. pH is defined as the inverse of the base 10 logarithms of the activity of the \[{{H}^{+}}\] ion.
Solutions with a pH less than \[7\] are acidic, while solutions with a pH greater than \[7\]are basic at \[{{25}^{{}^\circ }}C\]. At this temperature, solutions with a pH of \[7\] are neutral (e.g. pure water). The pH neutral value varies with temperature, falling below \[7\]as the temperature rises. For very strong acids, the pH value can be less than \[0\] and greater than \[14\] for very strong bases.
The pH scale determines how acidic or fundamental a material is. A basic pH is greater than \[7\]. As a result, each pH value less than \[7\] is ten times more acidic than the next higher value. The pH scale is logarithmic. For example, pH \[4\] is \[10\] times more acidic than pH \[5\], and 100 times (\[10\] times \[10\]) more acidic than pH \[6\].
In chemistry, PH is a measure used to specify the acidity or fundamentality of an aqueous solution. Acidic solutions have lower pH values than basic or alkaline solutions with higher \[{{H}^{+}}\] ion concentrations.
Thus, In this way pH Scale Measure Acidity.

Note:
The ideal pH for our blood and body tissues is around 7.2. (Because of the protein in the solution, saliva and urine test strips will show a much lower pH level.) A healthy body's saliva and urine tests should be between \[6.6\] and \[6.8\]) Acidosis is a condition in which there is too much acid in the blood and tissues.
