What colour does pH paper change to if sodium bicarbonate is added?
pH paper would change from red to yellow when sodium bicarbonate is added because sodium bicarbonate is a base and would increase the pH of the solution.
What is produce when you reacted sodium bicarbonate and sulphuric acid?
When sodium bicarbonate reacts with sulfuric acid, it produces sodium sulfate, carbon dioxide gas, and water.
What colour does universal indicator change to if sodium sodium by carbonate is added?
Universal indicator changes to green when sodium bicarbonate is added.
What is the function of sodium bicarbonate in esterification?
To remove the sulphuric acid (H2SO4) and carboxylic acid (RCOOH).
What colour of flame of sodium bicarbonate?
pink
Which colour is produced when universal indicator is added to sodium bicarbonate?
Baking soda is sodium bicarbonate or sodium hydrogen carbonate It is alkaline and will therefore turn universal indicator purple or blue
When sulphuric acid is passed through sodium bi-carbonate?
When sulfuric acid is passed through sodium bicarbonate, a chemical reaction occurs where carbon dioxide gas is produced, water is formed, and sodium sulfate salt is also produced. This is because sulfuric acid reacts with sodium bicarbonate to form carbonic acid, which decomposes to form water and carbon dioxide gas. The leftover sodium ions combine with the sulfate ions from the sulfuric acid to form sodium sulfate salt.
What is the reaction when sodium bicarbonate and concentrated sulphuric acid are mixed?
When sodium bicarbonate is mixed with concentrated sulfuric acid, an acid-base reaction occurs. The bicarbonate ions in sodium bicarbonate react with the hydrogen ions in sulfuric acid to form carbon dioxide gas, water, and a sodium sulfate salt. This reaction produces effervescence (bubbling) due to the release of carbon dioxide gas.
What colour should sodium bicarbonate be in universal indicator?
Sodium bicarbonate would turn blue or purple in universal indicator solution, indicating a basic pH level, around pH 9-10.
Is sodium bicarbonate blue?
Sodium bicarbonate is white.
Are sodium bicarbonate and soda bicarbonate the same?
Yes, sodium bicarbonate and soda bicarbonate are the same compound. Sodium bicarbonate is commonly known as baking soda or bicarbonate of soda.
What is the melting point of sodium bicarbonate?
Sodium bicarbonate has a melting point of approximately 50 degrees Celsius (122 degrees Fahrenheit). At this temperature, sodium bicarbonate will change from a solid to a liquid state.
