Bases have a pH > 7.0 BUT this merely describes the concentration of ions. Strong usually describes if all the substance ionizes, not how many ions are present.
EX. NaOH is a strong base, but the pH of a solution of NaOH can be anywhere from 7.1 to 14 depending on how much has been dissolved.
A Base pH is from 8 to 14.
pH = 7 is neutrality
pH = 1 - 6 is acidic.
pH greater than 7. (7 is in fact the pH of neutral water.)
The pH scale numbers go from 0 to 14, 7 is neutral, and anything under 7 to 0 is an acid, and everything above 7 to 14 is a base
The pH scale goes from 1 to 14. Bases have a pH greater than 7.
Acidity is a pH under 7. High acidity is under 3.
Anything above 7 is basic.
Bases have a pH over 7.
a base
green indicates the pH value of 5-6 which is slightly acidic. for the whole pH color scale go to the reference cited.
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
we use the pH scale to find out if somthing is an acid or a base and how strong or weak it is.
pH Scale
it indicate the acid and base of the scale
pH=7 is the neutral point on the scale.
Bases are repestented by values greater than 7 on the pH scale.
The pH scale does not indicate the strength of the acid, so there is no number on the pH scale that indicates the strongest acid. A pH value of zero will be the most concentrated strong acid, but even that isn't exactly correct. Concentrations greater than 1 M have pH values <0, but are not useful values because of intermolecular interactions and activity values.
A base is anywhere from 8 to 14 on the Ph scale. If a base of about 8 is added to and acid of about 6, the Ph will be balanced out.
Nothing. pH values indicate acidity levels.
Anything from above 7 to 14 is a base on the pH scale
A soluble base is an alkali, so above 7 on the pH scale.
The strongest base is the hydroxide ion, in the pH scale 0 to 14.
Massive acidity.
7-14 is the range of base in a pH scale
