weak electrolytes gives weak value of pH scale.
any thing with a pH below 7 is an acid and anything with a pH above 7 is a base. So a weak base would be around 8
The pH of a weak acid depends on its concentration. A weak acid solution with a higher concentration will have a lower pH, while a lower concentration will result in a higher pH. The pH can be calculated using the acid dissociation constant (Ka) of the weak acid.
very weak bases
No, it isn't. That's a weak base. A strong base is a 9.1 - 14.0 on the pH scale.
Ammonia itself is a weak base and typically has a pH around 11-12 when dissolved in water.
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
its an alkali, the other side of the pH scale you numpty;)
Citric Acid is a weak acid. It is round about 6 on the pH scale.
The pH range of an acid is typically below 7 on the pH scale. Strong acids have a pH closer to 0, while weak acids have a pH closer to 7.
Depending up on the ph of solution.if the ph of solution is less than 7 in ph scale it can acts as acid.the acidity increases from 6.9 to 1.
on a PH scale 7 is neutral. So any number close to 7 is considered weak be it a base or an acid.
If you are using the common English definitions of "strong" (meaning 'more') and "weak" (meaning 'less'), then a strong base will have a pH of 12-14 while a weak base will have a pH of 7-9. However, there is a specific scientific definition of 'strong' and 'weak' when used to describe acids and bases. In chemistry, a 'strong base' is a base that completely ionizes in water while a 'weak base' is a base that partially ionizes in water. If you are using these definitions, there is no way to categorically compare the pH of a strong base versus the pH of a weak base - the two variables do not related. Some strong (complete ionization) bases will have a lower pH (7-9) while other strong (complete ionization) bases will have a higher pH (12-14); the same is true of weak (partial ionization) bases.
