Weak bases tend to build up in acidic fluids.
Have those weak bases.
The resulting anion(SbF- 6)is both a poor nucleophile and a weak base.
A strong acid reacts with a weak base to form an acidic pH.
Like other amines,methanolamine acts as a weak base.
A strong acid reacts with a weak base to form an acidic(pH<7) solution.
For example, sodium acetate is a weak base.
A strong acid reacts with a weak base to form an acidic(pH<7) solution.
Weak bases, such as soda or egg white, should be used to neutralize any acid spills.
Polyphosphates are weak bases.
As the salt of a weak acid and a weak base, Ammonium Acetate has a number of distinctive properties.
Priestley called the compound"alkaline air," because his solution showed the properties of a weak base.
When a weak acid reacts with a weak base an equilibrium mixture is produced.
Metal oxides, hydroxides, and especially alkoxides are basic, andcounteranions of weak acids are weak bases.
A typical reaction with dissolution involves a weak base, B, dissolving in an acidic aqueous solution.
This anion is classified as noncoordinating,because it is both a very weak nucleophile and a very weak base.
The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids(proton donors).
Metal oxides, hydroxides, and especially alkoxides are basic, andconjugate bases of weak acids are weak bases.
In solution, lead(II)hydroxide is a somewhat weak base, forming lead(II) ion, Pb2+, under weakly acidic conditions.
An example is the weakly acidic ammonium chloride, which is produced from the strong acid hydrogen chloride and the weak base ammonia.
In terms of its acid-base properties,chloride is a very weak base as indicated by the negative value of the pKa of hydrochloric acid.
Resonance stabilization, however, enables weaker bases such as carboxylates; for example,sodium acetate is a weak base.
Being an analog of pyridine,isoquinoline is a weak base, with a pKa of 5.14.
When a weak acid reacts with a weak base, the endpoint solution will be basic if the base is stronger and acidic if the acid is stronger.
Acid urine, compared to alkaline urine,excretes weak bases at a faster rate.
In the first example, cyclization to an oxirane always compete with formation of thietane, butthe higher nucleophilicity dominates especially if one uses a weak base.
This is characteristic of the dissolution of weak acids or weak bases in aqueous media of varying pH.
The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids(proton donors): H++ NH3→ NH+ 4 The ammonium ion is mildly acidic, reacting with Brønsted bases to return to the uncharged ammonia molecule: NH+ 4+ B-→ HB+ NH3 Thus, treatment of concentrated solutions of ammonium salts with strong base gives ammonia.
Stainless steel remains unaffected by any of the weak bases which include ammonium hydroxide even at high concentrations and high temperatures.
