What value is used to express the acidity or icity of a solution called?
The acidity and the basicity are expressed by pH (the negative logarithm of the hydronium ion activity).
Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
How are pH and logarithm related?
pH =-log[H+]
Does the pH scale measure the concentration of hydroxide ions?
Yes, if you use a little bit of math. Take 14 minus your pH and you get the negative decadic logarithm of the hydroxide concentration.
How is a change in hydrogen ion concentration reflected in the pH?
pH is the negative logarithm of the hydrogen ion concentration; so an increase in hydrogen ion concentration give a reduction in pH. A reduction in hydrogen ion concentration causes an increase in pH.
What the PH?
negative logarithm of hydrogen ion concentration
What are characteristics of pH?
pH is the negative logarithm of the hydrogen ion activity in a solution.
Is the pH of solution is the negative logarithm of its hydroxide ion concentration?
No, the pH is the negative logarithim to base 10 of the Hydrogen Ion concentration.
Why is there a minus sign on the definition of pH?
pH of a solution is the negative logarithm of the hydrogen-ion concentration
What is the formula of calculating pH?
pH = - log [H3O+]. It is the negative logarithm of the hydronium ion concentration.
What value is used to express the acidity or icity of a solution called?
The acidity and the basicity are expressed by pH (the negative logarithm of the hydronium ion activity).
How can hydrogen be used as pH indicators?
The negative logarithm of the hydrogen ions activity is a measure of pH in the solution.
How do you calculate from scientific notation to pH?
take the negative logarithm ex. 10^-4 has a pH of 4
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).
Why you need pH?
pH is used as a measurement of the concentration of hydrogen ions in a solution. pH is the negative logarithm of the hydrogen ion concentration.
What does pH equal mathematically?
The negative logarithm of the molar concentration of hydronium (H3O+) ions. pH=-log[H3O+]
how does the pH scale is a mathematical indicator of?
The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
