Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
Sodium chloride, NaCl, for example is of neutral pH and conductive in solution or in molten state. It is a salt.
A substance with a pH balance of 7 is considered neutral. This means that it is neither acidic nor basic. Pure water at room temperature has a pH of 7.
Neutralization occurs, with heat and water being produced as well as a compound. The compound may be soluble and is invisible in the water or insoluble and appears in the bottom of the solution. The pH of the resulting solution would be anywhere between 5 and 14 depending on the amount of both substance added. If the pH of the final solution is less than 7, some of the acid (in this case a pH 5 substance) will be left in the solution and the reverse applies as well. If the pH of the final solution is 7, there would be no more acid or alkali left (since they are totally neutralized)
Water is commonly used as a solvent in a pH solution because it is a neutral substance that can dissolve a wide range of solutes. It is able to maintain the pH of a solution by providing a medium for the acidic or basic components to be dispersed and interact with each other.
For example an alkali metal.
pH is the measure of the levels of acid or base in a substance. Increasing the amount of a substance will not change the pH so long as the existing substance and the added substance are chemically the same.
pH of 1 to < 7 indicates an acid pH of >7 to 14 indicates a base pH of 7 indicates water
is a basic compound that when dissolved in water, forms a solution with a pH greater than 7. The pH of 9 indicates that the solution is moderately alkaline.
Sodium chloride, NaCl, for example is of neutral pH and conductive in solution or in molten state. It is a salt.
Acid
The pH of a substance tells if it's an acid, neutral, or a base. With all deference to the asker and to the previous answerer, technically substances don't have pH's. Aqueous solutions have pH's, and the pH tells you (on a logarithmic scale) the concentration of H+ (or more precisely H3O+) in that solution. A substance is an acid if it lowers the pH of a solution when it is dissolved. It does this by donating protons (H+'s) to water molecules to create more H3O+. A substance is a base if it increases the pH of a solution by accepting a proton from water molecules to form OH-. H3O+ and OH- are in equilibrium with each other in solution, so the more OH- you create, the less H3O+ will be in solution and the higher the pH. So a better answer to the question is that "The pH of a solution tells you if its an acidic, neutral, or basic solution."
When a substance is dipped into a pH solution, it will either change color due to a chemical reaction with the solution, or it may not show any visible change if the substance is neutral. This process helps determine the acidity or basicity of the substance based on the pH solution's color change.
A substance with a pH balance of 7 is considered neutral. This means that it is neither acidic nor basic. Pure water at room temperature has a pH of 7.
Generally a neutral substance is called an inert substance.
A base is a substance that forms hydroxide ions in water and has a pH above 7. Bases are known for their ability to neutralize acids and have a bitter taste. Some common examples of bases include sodium hydroxide and ammonia.
A substance is classified as an acid or a base, based on the pH of the substance. pH is the rating of a substance compared to water, which is considered neutral. Water has a pH of 7.0. A substance with a pH less than water is considered acid and higher than water is considered a base. The pH of a substance is determined by a mathematical formula that represents the concentration of hydronium ions in a solution.
Neutralization occurs, with heat and water being produced as well as a compound. The compound may be soluble and is invisible in the water or insoluble and appears in the bottom of the solution. The pH of the resulting solution would be anywhere between 5 and 14 depending on the amount of both substance added.
