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.
What else can I help you with?
Are acid base neutral substances?
No, they are not. An acid is acidic in nature which means it has more H+ ions than OH- ions. But a base is basic in nature which means that it contains more no. of OH- ions than H+ ions.
What are acids alkali and neutral?
Acids are substances that release hydrogen ions in solution, have a pH below 7, and can neutralize bases. Alkalis, also known as bases, accept hydrogen ions in solution, have a pH above 7, and can neutralize acids. Neutral substances have a pH of 7 and are neither acidic nor alkaline.
Are all substances either acidic or basic?
No, not all substances are either acidic or basic. Some substances are neutral, meaning they have a pH of 7. Acidic substances have a pH below 7, basic substances have a pH above 7, and neutral substances have a pH of 7.
What are the pH values of acids Bases?
Acids have pH values below 7.0. Bases have values above 7.0.
What was arrehenius concept of acids and bases?
Svante Arrhenius' concept of acids and bases, proposed in 1884, defined acids as substances that dissociate in water to produce hydrogen ions (H+) and bases as substances that dissociate in water to produce hydroxide ions (OH-). He proposed that a substance's ability to form ions in solution determined whether it was an acid, base, or neutral. This theory laid the foundation for modern theories of acids and bases.
Are acid base neutral substances?
No, they are not. An acid is acidic in nature which means it has more H+ ions than OH- ions. But a base is basic in nature which means that it contains more no. of OH- ions than H+ ions.
What is true about bases on the pH scale?
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
How can you distinguish among acids bases and neutral substances?
The simplest method is to determine the pH with a pH-paper or a pH-meter.
What are acids alkali and neutral?
Acids are substances that release hydrogen ions in solution, have a pH below 7, and can neutralize bases. Alkalis, also known as bases, accept hydrogen ions in solution, have a pH above 7, and can neutralize acids. Neutral substances have a pH of 7 and are neither acidic nor alkaline.
What is the between acids and bases?
Neutral
Are esters acids bases or neutral?
Esters are neutral compounds
Are all substances either acidic or basic?
No, not all substances are either acidic or basic. Some substances are neutral, meaning they have a pH of 7. Acidic substances have a pH below 7, basic substances have a pH above 7, and neutral substances have a pH of 7.
What is the way a person can distinguish among acids bases and neutral substances?

What do acids react with to form a neutral solution?
Acids react with bases to form a neutral solution. This reaction typically produces water and a salt compound.
Is water neutral between acids and bases?
Yes.
