U+33D7 Square Ph

U+33D7 was added in Unicode version 1.1 in 1993. It belongs to the block U+3300 para U+33FF CJK Compatibility in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Otro símbolo and is commonly used, that is, in no specific script.

The glyph is a square composition of the glyphs Glifo para U+0050 Latin Capital Letter P, Glifo para U+0048 Latin Capital Letter H. Its East Asian Width is wide. In bidirectional text it is written from left to right. When changing direction it is not mirrored. U+33D7 offers a line break opportunity at its position, except in some numeric contexts.

El Wikipedia tiene la siguiente información acerca de este punto de código:

In chemistry, pH ( pee-AYCH), also referred to as acidity or basicity, historically denotes "potential of hydrogen" (or "power of hydrogen"). It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic solutions (solutions with higher concentrations of hydrogen (H+) ions) are measured to have lower pH values than basic or alkaline solutions.

The pH scale is logarithmic and inversely indicates the activity of hydrogen ions in the solution

pH=log(aH+)log([H+])

where [H+] is the equilibrium molar concentration (mol/L) of H+ in the solution. 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 25 °C 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 and is lower than 7 if the temperature increases above 25 °C. The pH range is commonly given as zero to 14, but a 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.
