What does the pH scale tell about a solution?
it tells you if the solution is an acid or alkaline.
How is the pH scale used to determine if a substance is acidic or basic?
pH tells you the amount of hydrogen ions in a solution. Acidic solutions have a pH less than 7 and more H+ ions. Basic solutions have a value over 7, and contain fewer H+ ions.
What is the scale called that measures the acidity or basicity of a solution?
litmus paper. it changes color depending on the amount of hydrogen ions present in the solution. higher amount of H+ ions, its acidic and will have a lower number on the pH scale. and vice versa for basesAdded:Comment:An indicator for pH, like lithmus paper, can only tell IF a solution is acidic or basic, it can NOT measure HOW acidic (or basic) it is.The best measurement is done in the electro-chemical way: pH-measure device (pH-meter) on the '0 to 7 to 14' scale: (arbitrarely classified, based on experience)pH 0 - 2: very - rather strong acidicpH 3 - 6: rather weak - very weakly acidicpH = 7 : neutralpH 8 - 10: very weak - rather weakly basicpH 11 - 14 rather strong - very strong basic
What does pH of a solution represent?
The pH indicates how acidic or basic a solution is.
What is a pH test normally used for?
A pH test is used for finding the concentration of hydronium ions in a certain solution. It tells how acidic or basic a solution is with a value that is known as pH.

What does pH of a solution represent?

Which of these is numerical measurement that tells how acidic or basic a solution is?
The acidity/basicity is measured with a pH-meter; a pH under 7 is acid and a pH over 7 is basic.

A pH test is used for finding the concentration of hydronium ions in a certain solution. It tells how acidic or basic a solution is with a value that is known as pH.
What does substance's pH tell you?
Ph tells you how acidic/basic a solution is. It is a measure of the relative concentrations of H+ ions to OH- ions.
What is pH of a substance?
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."
What is the definition for a distance scale?
a scale that tells the distance
What does a low number on the pH scale tell us about a solution?
The solution is an acid.
When would litmus paper be useful?
It helps in indicating whether a substance is acidic or basic A red litmus paper turns blue in basic solution and turns red in acidic solution A blue litmus paper turns red in acidic solution and turns darker blue in basic solution
What information does pH of a solution give?
pH of a solution tells us about the nature of a solution( i.e acidic or basic ) if pH of a solution is less than 7 tahn it's acidic if it's 7 then it's neutral and more than seven will make it base.
