Lead hydroxide is not preferred as an alkali for the preparation of ammonia because it is a toxic substance and poses serious health hazards. Additionally, lead hydroxide can react with ammonia to form toxic lead compounds, further complicating the process. It is safer and more efficient to use other alkalis such as sodium or potassium hydroxide for this purpose.
What else can I help you with?
Is ammonia alkali?
Yes, ammonia is considered an alkaline substance. It can act as a weak base when dissolved in water, forming ammonium hydroxide.
Is ammonia solution acidic or alkali?
Ammonia solution is alkaline. It acts as a base when dissolved in water, producing hydroxide ions in solution and giving it its characteristic slightly slippery feel.
Is ammonia cleaning fluid acid or alkalis?
Ammonia cleaning fluid is considered alkaline because it has a pH level greater than 7. When dissolved in water, ammonia produces hydroxide ions, making it an alkali.
Which gas is formed when alkali is heated with ammonium salt?
Ammonia gas (NH3) is formed when an alkali, such as sodium hydroxide, is heated with an ammonium salt, such as ammonium chloride.
Do all bases contain hydroxide ions?
A BASE is a metal oxide. A soluble base is an ALKALI and contains hydroxide ions. (-OH) Sodium oxide (Na2O) is a BASE Sodium hydroxide (NaOH) is an ALKALI. The alkali comes about because the sodium oxide dissolved in water to form the alkali. Na2O + H2O = 2NaOH .
Is ammonia alkali?
Yes, ammonia is considered an alkaline substance. It can act as a weak base when dissolved in water, forming ammonium hydroxide.

Alkali react with ammonium salt?
I give an example for ammonium salt ....hmm.... lets just take ammonium chloride as an example . How about alkali ? I take calcium hydroxide as an example for alkali . Calcium hydroxide is formed when calcium oxide reacts with water whereas ammonium chloride is formed when hydrochloric acid reacts with ammonia solution . Calcium hydroxide (alkali) + ammonium chloride (ammonium salt) --> calcium chloride + carbon dioxide + water .
Give 5 examples of base?
Every hydroxide and carbonate of s-block elements excluding beryllium are alkali and several others are aluminium hydroxide and ammonia.
Do all bases contain hydroxide ions?
A BASE is a metal oxide. A soluble base is an ALKALI and contains hydroxide ions. (-OH) Sodium oxide (Na2O) is a BASE Sodium hydroxide (NaOH) is an ALKALI. The alkali comes about because the sodium oxide dissolved in water to form the alkali. Na2O + H2O = 2NaOH .
Will H2O and NH3 form a solution?
H2O (water) and NH3 (ammonia) can mix and form a homogeneous solution in certain circumstances, such as when diluting ammonia in water or using them as solvents. However, ammonia is a weak base and can react with water to produce ammonium and hydroxide ions.
What things are alkali?
Alkali's are soluble bases. Bases are the oxides of Groups (I) & (II) metal elements. Taking Group (I) sodium oxide (Na2O) , this is a BASE . It dissolved in water to for the hydroxide , an Alkali. Na2O + H2O = 2NaOH an alkali. However taking Group (II) Calcium oxide (CaO), this is a BASE. It is sparingly soluble in water to form the hydroxide , an Alkali. CaO + H2O = Ca(OH)2 an alkali.
Is ammonia is an acid?
Ammonia is a weak alkali, it is not acidic.
What stuff contain strong alkali?
Some common substances that contain strong alkali include sodium hydroxide (caustic soda), potassium hydroxide (caustic potash), and ammonia. These substances are highly corrosive and can cause severe burns or damage to living tissues.
Is ammonia a strong alkali?
Yes, ammonia is a weak alkali. It is a weak base that can accept a proton to form the ammonium ion.
