what happens to washing soda crystals when mixed with sulphuric acid
The two substances would cancel them selves out as washing soda crystals are an alkali and sulphuric acid is an acid. But remember they will only counsel them selves out if there the exact same amount . This is because say we had 8ml of acid and then only 7.5ml of alkali the mixture would be slightly acidic. Hope this helps.
When washing soda crystals (sodium carbonate) are mixed with sulfuric acid (H2SO4), a chemical reaction takes place. Here are the steps involved:
Step 1: Dissociation of washing soda crystals:
When washing soda crystals are dissolved in water, they dissociate into sodium ions (Na+) and carbonate ions (CO3^2-). The dissociation reaction is as follows:
Na2CO3 (s) + H2O (l) -> 2Na+ (aq) + CO3^2- (aq)
Step 2: Acid-base reaction:
Sulfuric acid is a strong acid, and it donates a hydrogen ion (H+) when dissolved in water. The hydrogen ion reacts with the carbonate ion from the washing soda, resulting in the formation of carbonic acid (H2CO3).
H2SO4 (aq) + CO3^2- (aq) -> H2CO3 (aq) + SO4^2- (aq)
Step 3: Decomposition of carbonic acid:
Carbonic acid (H2CO3) is unstable and easily decomposes into water (H2O) and carbon dioxide gas (CO2):
H2CO3 (aq) -> H2O (l) + CO2 (g)
Step 4: Formation of sodium sulfate:
The sulfate ion (SO4^2-) from the sulfuric acid reacts with the sodium ion (Na+) from the washing soda, resulting in the formation of sodium sulfate (Na2SO4):
2Na+ (aq) + SO4^2- (aq) -> Na2SO4 (aq)
In summary, when washing soda crystals (sodium carbonate) are mixed with sulfuric acid, carbon dioxide gas is released along with the formation of sodium sulfate.
When washing soda crystals (sodium carbonate) are mixed with sulphuric acid (H2SO4), a chemical reaction occurs. The reaction can be described as follows:
Na2CO3 (sodium carbonate) + H2SO4 (sulphuric acid) → Na2SO4 (sodium sulphate) + CO2 (carbon dioxide) + H2O (water)
In this reaction, the sodium carbonate reacts with the sulphuric acid to form sodium sulphate, carbon dioxide, and water. The washing soda crystals dissolve in the acid, releasing carbon dioxide gas as bubbles and forming a solution of sodium sulphate.
To understand why this reaction occurs, you can break it down into the ions involved:
Na2CO3 → 2Na+ + CO3^2-
H2SO4 → 2H+ + SO4^2-
The positive sodium ions (Na+) from the washing soda react with the sulphate ions (SO4^2-) from the sulphuric acid, forming sodium sulphate (Na2SO4). Meanwhile, the carbonate ions (CO3^2-) from the washing soda react with the hydrogen ions (H+) from the sulphuric acid, forming carbon dioxide (CO2) and water (H2O).
So, when washing soda crystals are mixed with sulphuric acid, sodium sulphate, carbon dioxide, and water are produced as a result of the chemical reaction.
