What substance on the pH scale is neutral and how do you know?
By definition, a pH of 7 is "neutral" and corresponds to pure water. Most pH measurement is done on aqueous solutions.
Why is a pH scale called a pH scale?
The pH scale is a scale to express the acidity of aqueous solutions (i.e. anything dissolved in water). The scale is divided in equi-distantial units with decimals, comparable with temperature or pressure scales. Commonly it goes from 0 - 14, with 7 being neutral. pH stands for parts of hydrogen. It is the negative log of the hydrogen ion concentration.
What is calcite on the pH scale?
Calcite does not have a pH. The pH scale determines how acidic or basic an aqueous solution is meaning solution in which the solvent is water.
What is 'Hammett acidity function'?
The Hammett acidity function (H0) is a measure of acidity that is used for very concentrated solutions of strong acids, including superacids. It was proposed by the physical organic chemist Louis Plack Hammett and is the best-known acidity function used to extend the measure of acidity beyond the dilute aqueous solutions for which the pH scale is useful.
Why you directly not measure the pH of organic solvent?
pH is defined only in diluted aqueous solutions. The pH scale, 0 - 14, comes from the dissociation of water (Ka = 10-7). In non-aquous solutions there is no water so this scale is not valid. The only way for direct pH measurement is using a normal pH sensitive electrode (glass, ISFET, enemal, ...) and use a selective electrode sensitive to other compounds in the solution (salts, ions, ...) wich are not affected by pH change.
Does oil have a pH?
No. The pH scale is a measure of acid in aqueous solutions, meaning that the solution needs to be mostly water. Since oil has nearly zero water, the pH scale is irrelevant.
What number range can you find an acid-in on the pH scale?
Acidic solutions have a pH under 7.

What colour is red litmus in pH scale?
Blue litmus paper will turn to red because hydrochloric is an acid. In aqueous solutions,acid change blue litmus paper to red. In aqueous solutions,base change red litmus paper to blue.
What is the scale used to clarify the strength of acid or basic solutions?
This scale is the pH scale.
The scale used to classify the strength of acid and basic solutions?
The pH scale.
What is pH scate?
numeric scale used to specify the acidity or alkalinity of an aqueous solution

A multirange voltmeter which scale is numbered from 0 through to 250 the pointer falls mid range on the scale interpret the reading on the meter?
With the pointer mid range on the scale, the reading of the multi-range voltmeter would be 125 volts.With the pointer mid range on the scale, the reading of the multi-range voltmeter is 125 volts.
Define nano devices?
Nano devices are devices made from nanomaterials and whose scale is reasonably measured in nanometers. Generally this range is from 1 to 100 nanometers.
