Assuming that the solvent is water, then NH4Cl (aq) is weakly acidic. This is because the Ammonium ion is Bronstead-Lowry acidic: it can donate H+ to give a neutral NH3 molecule. NH4(+) + H2O <----> NH3 + H20 + H(+) (Reversible reaction) If NH4Cl (ammonium chloride) is added to the solution, this will increase the concentration of NH4+. Since there is greater concentration of NH4(+), more H(+) ions will be released into solution, decreasing the pH, increasing the pOH, and thus making the solution acidic. Therefore a solution of any ammonium salt in water, not just ammonium chloride, is weakly acidic.
Basic. Like ammonia, amines are able to accept an H+ ion from water, forming an ammonium ion and a hydroxide ion. Substances that accept H+ ions are (by definition) bases, and the formation of OH- in aqueous solution causes the solution to have a pH above 7, which makes it basic.
Metal oxides are bases. So when dissolved in water they will become a basic solution.
NB Non-metallic oxides form acidic solutions.
e.g. CaO + H2O = Ca(OH)2 an alkaline solution.
e.g. SO2 + H2O = H2SO3 (Sulphurous ACID)
NB. Aluminium oxide is amphoteric it can form an acid or alkali depending on its environmental pH.
Yes the water become acidic
They are nonreactive towards each other in aqueous solutions but separately in acidic medium sodium benzoate forms the benzoic acid and ammonium chloride forms ammonia in basic medium.
neither, a common salt solution is neutral
more acidic e.g from Na(basic) to P(acidic)
No, it forms a basic solution containing ammonium hydroxide.
define BE (Be -2 to 2 )
acidic
The solutions of chlorides and sulphates of heavy metals are acidic in nature so solution of copper (II) chloride is also acidic in nature.
acidic
No, ammonium nitrate is acidic.
its acidic
Sodium chloride solution is neutral.
A buffer solution is a solution that resists changes in pH caused by the addition of acid or alkali. There are two types of buffers: 1. Acidic 2. Basic Acidic buffers comprise of a weak acid and its salt. eg. ethanoic acid and sodium ethanoate. Basic Buffers comprise of a weak base and its conjugate salt. eg. aqueous ammonia and ammonium chloride.
They are nonreactive towards each other in aqueous solutions but separately in acidic medium sodium benzoate forms the benzoic acid and ammonium chloride forms ammonia in basic medium.
It may be white solid Ammonium chloride NH4Cl, formed by Acidic gas HCl and Basic gas NH3.
The ammonium ion (NH4+) is mildly acidic. It is not to be confused with ammonia (NH3), which is basic
Fertilizers are usually basic compounds but solution of some as Ammonium nitrate and sulphate are slightly acidic.
The pH scale measures how acidic or alkaline (basic) a solution is.
