1. 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);

1. 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.

1. 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

1. Gerald Keefe:

   These companies have achieved scale quickly and now increasingly are growing in developed markets.

2. John Fetterman:

   We're the party that doesn't want to criminalize things like marijuana, small-scale marijuana possessions. We don't want to criminalize. We want to get rid of cash bail where it's appropriate, so we don't criminalize poverty, we don't criminalize race.

3. Chris Mason:

   If the AMD trials are successful, then by using embryonic stem cells as the starting material, the therapy can then be affordably manufactured at large scale.

4. Stuart Graham:

   We believe Mr Cryan will be able to review the size and scale of the investment bank with a much harsher lens than Mr Jain, the execution risk is higher than normal at Deutsche, but so too is the investor unhappiness. We therefore expect the shares to out-perform, at least for the next few months, on the back of this cathartic management change.

5. Dan Thelander:

   We'll have to lay off employees. We won't be buying as many seeds or fertilizer or tractors, and so we'll just have to scale down and operate a smaller farm, and so, yes, it'll hurt a lot.
