A strong base is a substance that dissociates completely into its ions and gives a solution with high hydroxyl ion concentration. Learn about the seven strong bases, their uses and how to identify ...
Whether magnesium hydroxide is a strong or weak base is a matter of disagreement. Usually it is considered a weak base because of its low solubility. Whether it's a strong or weak base in terms of dissociation is not completely known. IUPAC reports a single $\mathrm{p}K_\mathrm{b}$ value, generally between 2 and 3, based on hydrolysis ...
The conjugate base of a strong acid is generally a weak base. And vice-versa if you swap all occurences of acid and base. The word generally is required here, since compounds such as $\ce{H2Cl+}$ are very strong acids whose conjugate bases are still very strong — but these compounds are not typically easily accessable and certainly not in ...
Amounts of weak acid and weak base. Also, shouldn't the buffer solution have a common ion? You start with $\pu{10 mmol}$ of ammonium salt (weak acid), to which you add $\pu{7.5 mmol}$ of $\ce{NaOH}$. The result is $\pu{7.5 mmol}$ of ammonia (weak base) with $\pu{2.5 mmol}$ ammonium salt remaining. So the ratio of weak base to weak acid is 1:3.
Another strong base is potassium hydroxide with the chemical formula of KOH. This is a basic substance with a pKb of 0.5. This is a common base in alkaline batteries and many soaps and detergents ...
There is no sharp boundary between weak and strong acid. Wikipedia defines strong acids as acids which ionize completely in aqueous solution . So, an acid, say $\ce{HA}$ , is said to be strong if one mole of this acid dissociates in aqueous solution to give one mole of $\ce{H+}$ and one mole of $\ce{A-}$ .
This strong acid-strong base titration curve looks different than if one component was a weak acid or base in a few ways. First, the equivalence point is pH of 7 in this case, which means the ...
When the number of moles of added base is equal to the number of moles of added acid (or vice versa; example valid for strong monoprotic acids/bases assuming 100% dissolution), the pH is equal to 7. You might say, if the pH needed is 7, and phenonphthalein changes at pH's around 8.2, how can you use this indicator?
t-BuOK is especially known as a strong base, and a poor nucleophile. Its large, bulky structure causes it to perform exceptionally poorly in substitution, literally eliminating any side reactions when the desired product is the elimination product. It is easily available, like Raphaël insists. It's basic strength depends on the medium.
Strong Base Solution: Strong bases can completely dissolve in water. Their pH value is extremely high, usually between 12 to 14. Group 1 alkali metals reacted with water and give strong bases. For ...
