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 bases
Added: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 acidic
pH 3 - 6: rather weak - very weakly acidic
pH = 7 : neutral
pH 8 - 10: very weak - rather weakly basic
pH 11 - 14 rather strong - very strong basic

What value is used to express the acidity or icity of a solution called?
The value used to express the acidity or basicity of a solution is called pH. pH stands for "potential of hydrogen" and is a measure of the concentration of hydrogen ions in a solution. A pH value below 7 indicates acidity, while a pH above 7 indicates alkalinity.
Is a scale that measures the acidity or basicity of a solution along a range of zero to 14?
The pH scale measures the acidity or basicity of a solution on a scale of 0 to 14. A pH of 7 is considered neutral, while lower values indicate acidity and higher values indicate basicity. The scale is logarithmic, so each unit change represents a tenfold difference in acidity or basicity.
What is a negative logarithm of the hydrogen ion concentration expressed in moles per liter called?
The negative logarithm of the hydrogen ion concentration expressed in moles per liter is called the pH value. It represents the acidity or basicity of a solution, with values below 7 indicating acidity, a pH of 7 indicating neutrality, and values above 7 indicating basicity.
What is the measurement called when measuring acid?
The measurement of acidity is called pH. It is a scale that measures the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating lower acidity.
What measures a solution and ability to neutralize acid?
pH measures the acidity of a solution. A solution with a low pH value (0-6) is acidic, a pH value of 7 is neutral, and a pH value above 7 is basic. Substances that can neutralize acids are called bases.
Are substances that change color with respect to the acidity or basicity of a solution?
These substances are called pH indicators.
What value is ued to express the acidity or bacity of a solution called?
The acidity or basicity are expressed by pH (the negative logarithm of the activity of hydronium ion).

Concentration of hydrogen ions in solution is called?
The concentration of hydrogen ions in solution is called pH. It is a measure of the acidity or basicity of a solution on a scale from 0 to 14, with lower values indicating acidity and higher values indicating alkalinity.
Why is pH called pH?
It's from the French: pouvoir hydrogen (literally, the Power of Hydrogen).
What is a negative logarithm of the hydrogen ion concentration expressed in moles per liter called?
The negative logarithm of the hydrogen ion concentration expressed in moles per liter is called the pH value. It represents the acidity or basicity of a solution, with values below 7 indicating acidity, a pH of 7 indicating neutrality, and values above 7 indicating basicity.
The pH scale measures?
The pH scale isn't used for measuring anything. It tells if a substance is an acid or a base. On the pH scale, 7 or more is considered a base. lower than 7, on the pH scale is considered an acid. Acids are usually sour, sweet, or have a very sweet, bitter taste. Usually Bright colors. And Bases are mostly poisons. THey have a horrible bitter taste. Some can kill you if inhaled or consumed.
What is the measurement called when measuring acid?
The measurement of acidity is called pH. It is a scale that measures the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating lower acidity.
What measures a solution and ability to neutralize acid?
pH measures the acidity of a solution. A solution with a low pH value (0-6) is acidic, a pH value of 7 is neutral, and a pH value above 7 is basic. Substances that can neutralize acids are called bases.
What compound changes color when in contact with an acid or a base this is called?
An acid-base indicator is a compound that changes color depending on the acidity or basicity of the solution it is in contact with. Examples include litmus, phenolphthalein, and bromothymol blue.
Why does acid and bases always form water when combined?
When an acid and a base combine, they undergo a chemical reaction called neutralization. In this reaction, the acidic hydrogen ion (H+) from the acid combines with the basic hydroxide ion (OH-) from the base to form water (H2O). This process neutralizes the acidity or basicity of the solution.
