no they alkaline solutions have a pH higher than 7
No, acids do.
Alkalis will produce a pH above 7.
No - acids and alkalis are "opposites". Acids have a pH less than 7 (which is the pH of water which is neutral) and alkalis have one over 7. Sulphuric acid comes in various strengths but often has a pH less than 1 and sometimes one which is negative.
acids -> hydrochloric acid, nitric acid, sulphuric acid alkalis -> sodium hydroxide, lithium hydroxide, potassium hydroxide an acid has a pH of less than 7 an alkali (or base) has a pH of more than 7
Acids have a pH level of less than 7.
Anything with a pH less than 7 is an acid. Anything with a pH greater than 7 is a base. pH = 7 is neutral
The definition of acidic is having a pH less than 7.
Acids have a pH under 7, alkalis have a pH bigger than 7.
great then 7
acids have a pH of less than 7, acid reacts with alkalis, acid turns litmus paper red. :)
Alkalines, or bases, have a pH greater than 7 (maximum is 14).
No - acids and alkalis are "opposites". Acids have a pH less than 7 (which is the pH of water which is neutral) and alkalis have one over 7. Sulphuric acid comes in various strengths but often has a pH less than 1 and sometimes one which is negative.

Look on the pH scale. Below 7 are acids, above 7 are alkali's!! ;-)
A pH of 7 is neutral A pH of less than 7 is acidic and a pH greater than 7 is basic.
Acids have a pH level of less than 7.
Anything with a pH less than 7 is an acid. Anything with a pH greater than 7 is a base. pH = 7 is neutral
An acid pH is anything less than 7 including zero.
