The pH scale exists from 0 to 14.The less the pH, more is the solution acidic and more the pH the more it is basic. 7 indicates neutral.

The pH scale measures hydrogen ion (H+) concentration in a substance. For example, water (H2O) has a neutral pH of 7. Some of the water molecules will naturally dissociate (or break apart), forming hydrogen ions (H+) and hydroxyl ions (OH-). So you have positive and negative charges. In water, there are approximately the same number of H+ and OH- ions (as well as neutral H2O molecules and, as such, the pH is said to be neutral.
Acids donate H+ (or increase the H+ concentration), which means there are more H+ ions floating free in the mixture and the overall charge of the substance is positive (due to all those extra positive ions floating about). A pH of less than 7 is acidic.
Bases (or alkaline substances) accept H+ ions, meaning there is a lower concentration of H+ and the solution has an overall negative charge. A pH of more than 7 is basic.
You can apply the pH scale to solutions to determine its acidic or basic nature (or how well it frees up or binds to H+ ions). Because the pH scale is logarithmic, a small change in pH means a big change in concentration. For example, a pH of 7 equals a H+ concentraion (relative to water) of 1. A pH of 6 is equal to a H+ concentration of 10, pH 5 is equal to H+ concentration of 100 and so on.
Acid, basic, and neutral are all on the pH scale of chemistry. On a scale of 1 to 14, 1 to 6 is acidic, 7 is neutral, and 8 to 14 is basic.
In 25 degrees celcius, 7-Neutral below 7-acidic above 7-basic
It is neither. It is a numeric scale used to tell how acid or basic an aqueous solution is. Water has a pH of 7 which is neutral. Acid in your stomach is nearly 1.
Acid has pH less than 7.0
Base has pH greater than 7.0
Neutral has a pH of 7.0
Acidic: a pH under 7
Neutral: pH=7
Basic: a pH over7
Acids - pH less than 7 Base - pH more than 7 Neutral - pH is 7
acids, salts, and bases have electrically charged ions in solution. neutral substances don't.
bases?
They are neutral
The pH level is from 1 to 14. 1 thru 6 is acids and 8 thru 14 is bases. Neutral means that it is neither an acid or a base. Water would be a neutral.
Acids - pH less than 7 Base - pH more than 7 Neutral - pH is 7
acids, neutral compounds, bases
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
The simplest method is to determine the pH with a pH-paper or a pH-meter.
Neutral
Esters are neutral compounds

Yes.
bases?
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
They either have a high concentration of H+ ions (acids) or OH- ions (bases). Strong acids and bases are also highly corrosive relative to weaker more neutral acids/bases.
