What is the pH scale based on?
pH scale ranges from 0 - 14. It measures the acidity or basicity of a solution. A measurement of 7 is neutral, less than 7 is acidic and a basic is higher than 7. pH is measured based on the concentration of hydroxide and hydrogen (or hydronium) ions in solution. A solution containing hydrogen (H+ ions) or Hydronium ions (H3O - which is made from the reaction of hydrogen ions with water) indicate a pH lower than 7 or an acidic solution. A solution containing hydroxide ions (OH-) creates a basic solution with a pH greater than 7. It is possible to measure a pH that is greater than the bounds of the scale since the calculation for the scale is based on the negative log of the concentration of hydrogen (or hydronium) ions in the solution. pH=-log[H3O] therefore [H3O] = 10^-pH
What value is used to express the acidity or alkalinity of a system?
Normally term,'PH' of a solution is used determine the strength of an acid which is nothing but the concentration of H+ ion concentration in a solution. ph= -log[H+] concentration.... since its -ve log hence smaller value of PH means it's more strong acid. ph=7 is value of water which is neutral. pH ranging below 7 are acids & above 7 are bases.
The scale used to classify the strength of acid and basic solutions?
The pH scale.
What does the pH scale measure the concentration of?
The pH scale is a Science indicator, Not a Mathmatical one :-)
What is the pH scale of a watermelon?
Watermelon has a pH of around 5.18 to 5.6. See Related Links.
What scale describes the acidity of a solution as a number?
the pH
PH of 4 than a solution with a pH of 5?
a pH of 4 is most acidic than a solution with a pH of 5. In general, the lower the pH, the more acidic the solution is.
What does the pH scale tell about a solution?
The pH scale measures the acidity or basicity of a solution on a scale from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic. The lower the pH, the more acidic the solution; the higher the pH, the more basic the solution.
What does red mean on the pH scale?
A red color on the pH scale typically indicates a highly acidic solution with a pH below 4. Factors such as litmus paper or pH indicators can help determine the color change corresponding to different pH levels.
How many Hydrogen ions does a solution with a pH of 4 have than a solution with a pH of 7?
A solution with a pH of 4 has 1,000 times more hydrogen ions than a solution with a pH of 7. pH is a logarithmic scale, so each decrease of 1 in pH represents a tenfold increase in hydrogen ion concentration.
What is a scale that measures the acidity or baseness of a solution?
pH scale measures the acidity or baseness of a solution. pH below 7 indicates acidity, while a pH above 7 indicates baseness. pH of 7 is considered neutral.
How many times more acidic is a solution of pH 1 than a solution having pH 2?
To first answer this question you must know how the PH scale works. Essentially the PH scale is a logarithmic scale. A logarithmic scale unlike a linear scale (you know the scales that go from 1, 2, 3, etc.) works using exponential increments. For the PH scale every time you go one number down the solution the item in question becomes ten times more acidic than the number above. Therefore to ultimately answer your question a solution with a PH of 1 is ten times more acidic than a solution that has a PH of 2.
What is the pH indicator scale?
it indicate the acid and base of the scale
How many more H plus ions does a solution with a pH of 4 have than a solution with a pH of 5?
A solution with a pH of 4 has 10 times more H+ ions than a solution with a pH of 5. This is because the pH scale is logarithmic, with each whole number representing a tenfold difference in H+ ion concentration.
What is listerine in the pH scale?
The listerine solution has a pH of approx. 4,5.
What does every unit on the pH scale represent?
Every unit represent the activity of the ion H+.
If something is a 0-6 on the pH scale what is it?
If something is a 0-6 on the pH scale it is an acid solution
