All acidity is due to hydrogen ions. The pH is the measure of the concentration present of these ions, but in reverse: the lower the pH, the higher the acidity. On a scale of 0 -14, a pH of 7 is neutral. Decreasing numbers indicate increasing acidity. Each number is ten times more acid than the preceding number (a negative logarithm is involved, but we need not understand the formula to understand the principle). Pure water has a pH of 7.
What else can I help you with?
What Does high pH mean on a pH scale?
A pH over 7 is basic.
What does acid and base mean?
Acidic solutions have a pH under 7.A neutral solution has a pH of 7.Basic solutions have a pH over 7.
What does acids bases and neutral mean?
Acidic solutions have a pH under 7.A neutral solution has a pH of 7.Basic solutions have a pH over 7.
What does acidic basic mean?
Substances are described as 'Acidic' if their pH < 7 Substances are described as 'Basic' if their pH > 7 Substances with a pH = 7 are described as neutral(a chemical salt). There is no such descriprtion as 'Acidic Basic'. They are contradictory!!!!
What does a basic pH mean?
@25'C ,pH higher than 7
What do mean pH scale?
The pH scale is from 0 to 14; pH is a measure of acidity/alkalinity of a solution.pH= 7 is neutral; under 7 is acidic, over 7 is alkaline.
What does the number seven mean on a pH scale?
it is neutral. Water is a 7 on the pH scale
What is a neutral pH mean?
The pH scale ranges from 0 to 14 such that something with a pH of 0 is extremely acidic and something with a pH of 14 is extremely basic. A neutral pH is in the middle and has a pH of 7. An example of something with a pH of 7 is rain water.
What kind of solution is produced acid or basic?
Your question is inadequate. If you mean to differentiate the two, you can do a pH test. If pH is below 7, it is acidic and if it is above 7, it is basic.If you mean to mix an acid and a base, following reaction will occur-Acid + Base ---> Salt + Water.
What is the hp for a neutral substance?
If you mean pH, the answer would be 7.
What do scale mean?
The pH scale is from 0 to 14; pH is a measure of acidity/alkalinity of a solution.pH= 7 is neutral; under 7 is acidic, over 7 is alkaline.
Does pH 7 mean neutral?
Yes, a pH of 7 is considered neutral, indicating a balance between acidic and basic substances in a solution.
