yes, almost total dissociation in water, the more OH negative hydroxide ions in solution, the more basic the solution is.
Both KOH and NaOH are strong bases. Both dissolve completely in water to produce equal concentrations of hydroxide ions.
No, it is weak.
it's a strong base
Neither, KOH is a strong base.
KOH is a strong electrolyte
KOH is a base
calcium hydroxide
Because the conjugate acid of a strong base is a much weaker acid than water. Since the conjugate acid is so weak, its chemical action as an acid is negligible in solution. Strong bases have very weak conjugate acids. Weak bases have relatively strong conjugate acids. The same is true for the conjugate bases of strong acids, such as HCl. Cl- is a much weaker base than than water, so its effects are also negligible.
Ammonium hydroxide is a weak base with the formula NH4OH. It readily forms when ammonia is dissolved in water but it can only exist in aqueous solution. Trying to isolate it will cause it to revert back to ammonia and water. Potassium hydroxide is a strong base with the formula KOH. It will readily dissolve in water but can also exist in a pure state, which takes the form of a white solid under normal conditions.
Sodium itself is neither an acid nor a base. However, it will react with water to form the strong base sodium hydroxide.
Here is a link to the make up of buffers from 1 to 13 . Scroll down for the pH 13 range, http://delloyd.50megs.com/moreinfo/buffers2.html ph 13 buffer needs to use Sodium Hydroxide. You can only get to pH 10 with Ammonia. Ammonia is only a 'weak' base to get to pH 13 you need a 'strong ' base ,strong bases are the Hydroxide's of Sodium, Potassium or other alkaline metals. Here is a link that explains the concept of weak and strong base's http://en.wikipedia.org/wiki/Base_(chemistry)
Ferric hydroxide is insoluble in water so it is a weak base.
Both KOH and NaOH are strong bases. Calcium hydroxide is not nearly so strong and NH4OH is a fairly weak base.
Potassium hydroxide is a strong electrolyte.
Rubidium hydroxide is a strong base as are all alkali metal hydroxides.
calcium hydroxide
Acid = Hydroiodic acid Base = Potassium hydroxide (or any Potassium salt of weak acid)
Sr(OH)2 is considered a strong base
To neutralise a strong acid, you would need a strong alkali (or lots of a weak alkali, but that would be impractical). Potassium hydroxide, sodium hydroxide, lithium hydroxide, calcium hydroxide, calcium hydroxide and magnesium hydroxide would all work.
Sodium hydroxide is a strong base and electrolyte.
phenolphthalein is a weak acid, when reacting with strong alkali it turns pink
it is a non electrolyte C2H5OH is not a base, its an alcohol, ETHYL ALCOHOL so its just an alcohol
The property of strong and weak, as far as chemistry of atoms is concerned, it pertains to the strong and weak bonds that exist between two or more atoms. A strong bond would indicate that a higher dissociation energy is needed to split the two; eg ionic bond. Whereas, a weak bond is one which can be easily broken; eg Hydrogen bond. Also, the properties of strong and weak are given to acids and bases in the same context. Acids which easily dissociate into ions are weak and which do not are designated as strong. Same holds true with bases. Examples; weak acid is carbonic acid, acetic acid. strong acid is sulphuric acid. Weak base is ammonia, methylamine. Strong base is sodium hydroxide, potassium hydroxide.
