In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...
The latter of the two cannibalized the Walmart-owned warehouse store to create one of the largest retail stores in the U.S., employing about 360 associates, according to Walmart.
In chemistry, pH (/ p iː ˈ eɪ tʃ / pee-AYCH), also referred to as acidity or basicity, historically denotes "potential of hydrogen" (or "power of hydrogen"). [1] It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.
Walmart Neighborhood Market, former also known as "Neighborhood Market by Walmart" or informally known as "Neighborhood Walmart", [153] is Walmart's chain of stores ranging from 28,000 to 65,000 square feet (2,600 to 6,000 square meters) and averaging about 42,000 square feet (3,900 square meters), about a fifth of the size of a Walmart ...
A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. [2] The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to as a "potentiometric pH meter".
A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution.

The pH of distilled water is always slightly lower than 7 (neutral) due to the fact that distilled water will absorb small amounts of carbon dioxide gas from the atmosphere which forms traces of carbonic acid and lowers the pH of distilled water to around 5.8 pH (very weakly acidic). [13]
