pH, pH scalenoun
(from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic);
Wikipedia
ph scale
In chemistry, pH (), historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution. pH = − log ( a H + ) = − log ( [ H + ] / M ) {\displaystyle {\ce {pH}}=-\log(a_{\ce {H+}})=-\log([{\ce {H+}}]/{\ce {M}})} where M = mol dm−3. At 25 °C (77°F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (i.e. have the same concentration of H+ ions as OH− ions, i.e. the same as pure water). The neutral value of the pH depends on the temperature – being lower than 7 if the temperature increases above 25 °C. The pH value can be less than 0 for very concentrated strong acids, or greater than 14 for very concentrated strong bases.The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. Primary pH standard values are determined using a concentration cell with transference, by measuring the potential difference between a hydrogen electrode and a standard electrode such as the silver chloride electrode. The pH of aqueous solutions can be measured with a glass electrode and a pH meter, or a color-changing indicator. Measurements of pH are important in chemistry, agronomy, medicine, water treatment, and many other applications.

ph scale
The pH scale is a logarithmic scale, ranging from 0 to 14, used to measure the acidity or alkalinity of a solution. A pH of 7 is considered neutral, values below 7 indicate increased acidity, and values above 7 indicate increased alkalinity. Each unit represents a tenfold change in acidity or alkalinity. The pH scale is widely used in chemistry, biology, and environmental science.

Examples of pH scale in a Sentence
This situation is a bit like secondhand smoke, but on a national scale.
There's been big movement in most of Europe's capitals in recognition of the scale of the challenge, that's decidedly what you're not getting from the' Frugal Four.' It's effectively a restatement of old positions.
They (aid agencies) will face difficulties in continuing to provide lifesaving health services at the scale that is required as a result mainly of the declining humanitarian funding.
We palaeontologists know that we can never find everything that ever once existed, but its unlikely something bigger in the shark world than megalodon ever existed or at least we would have clues about it — like a tooth or giant scale or something. Frankly nothing bigger than megalodon could have existed as there was likely not enough food to support it. It’s the same argument why lions are top of the food chain in Africa today.
This strike is not necessary, it will be damaging, we will do everything we can to mitigate its effects but you cannot have a strike on this scale in our NHS without real difficulties for patients and potentially worse.
