What is the meaning that the pH of a solution is 4.5?
It means that its an Acid. pH < 7 is acidic. pH > 7 is basic. pH = 7 is neutral.
Does a solution that has pH equals 7 has the same concentration of hydronium ions as a solution that has pOH equals 7?
Yes, if both solutions are at 25oC then in both solutions this is valid: pH + pOH = 14.0
What pH values indicates a solution with the highest concentration of hydrogen ions pH equals 1 or pH equals 2 or Ph equals 7or pH equals 14?
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
What does the term pH mean?
pH is the measure of the acidity or alkalinity pH means the power of Hydrogen. It is 'minus the decimal logarithm of the hydrogen ion activity in an aqueous solution'. The term was coined by Sørensen, it measures the alkalinity or acidity of a liquid. pH is a measure of the concentration of hydrogen ions [H+] in a solution. The concentration of the hydrogen ions is measured in Molarity (M), or moles of H+ ions per liter of solution. The pH is then expressed as the negative log (base ten) of the hydrogen ion concentration. pH = -log[H+] For example, if a solution has a hydrogen ion concentration of 4.75 x 10-5 M (or 4.75 x 10-5 moles of H+ ions per liter of solution), then the pH of the solution would be -log[4.75 x 10-5] = 4.323 pH is generally given on a scale from 0-14, with 0 being the most acidic solution (like HCl) and 14 being the most basic solution (for example, NaOH.), although extreme values may sometimes fall outside that range. Pure water has a pH of 7 because its H+ concentration is 1.0 x 10-7 M -log[1.0 x 10-7] = 7
What numeral value of pH is considered basic?
7 is neutral and greater than 7 is basic
When pH value of a solution is 7 then what is the nature of that solution?
If the pH value of a solution is 7 then the solution is basic. Anything below 7 is considered acidic and anything above 7 is considered alkaline or basic.
What would be the pH of a neutral solution An acid solution A basic solution?
Neutral solution: pH =7Acidic solution: pH7.
How does a solution with a pH of 7 compare to a solution with a pH of 9?
A solution with a pH of 7 compared to a solution with a pH of 9 would be more acidic.
When would a solution be considered a base?
When a substance goes above 7 on the pH scale, it is considered a base.
If a solution has a pH of 2 it would be considered?
Very acidic.A pH of 7 is considered neutral while anything above 7 is basic (alkaline) and anything under 7 is acidic.For every number on the pH scale, the change is ten-fold. So a solution with a pH of 2 is 10 times more acidic than a solution with a pH of 3.
What type of solution has a pH of 7.0?
A neutral solution would have a pH of 7.
How would you organize these in order pH concentration acid base and neutral?
pH = 0-7 acidic solution pH = 7 neutral solution pH = 7-14 basic solution
Which pH indicates a solution of an acid?
A pH less than 7 is considered acidic.
If you mix equal amounts of solution A with a pH of 2 and solution B with a pH of 8 is it acidic or basic?
A solution with a pH of 2 is strongly acidic. Remember, 7 is neutral, anything below 7 is acid, anything above 7 is basic or alkaline.
When the pH of a solution is 7.9 what is the solution described as?
Anything over 7 is considered basic
What is the acidic solution of pH?
Any aqueous solution will have a pH lower than 7.00 in order to be considered acidic.
What is the pH scale range for an alkaline solution?
Any pH >7 is considered basic or alkaline
