Color of sodium carbonate in universal indicator?
Sodium carbonate in universal indicator will typically appear blue or purple in color. This is due to the alkaline nature of sodium carbonate, indicating a high pH level.
How does the reaction between CO2 and NaOH affect the pH level of a solution?
When carbon dioxide (CO2) reacts with sodium hydroxide (NaOH), it forms sodium carbonate (Na2CO3) and water (H2O). This reaction increases the pH level of the solution because sodium carbonate is a basic compound.
What are the pH's of sodium carbonate and sodium bicarbonate?
The pH of sodium carbonate is around 11-12 due to its basic nature, while the pH of sodium bicarbonate is around 8-9 as it is slightly alkaline when dissolved in water. Both compounds are used as buffers and in various applications due to their pH properties.
What is the pH of sodium carbonate solutions?
The pH of sodium carbonate solutions is typically around 11-12, making it basic or alkaline.
How does the reaction between NaOH and CO2 affect the pH of a solution?
When NaOH reacts with CO2, it forms sodium carbonate and water. This reaction increases the pH of the solution because sodium carbonate is a basic compound. The presence of more basic compounds in the solution raises the pH level.
What is the pH level of sodium carbonate?
21 or 9

What is the purpose of adding sodium carbonate to the mixture?
Sodium carbonate is often added to a mixture to raise the pH level and increase the effectiveness of certain chemical reactions. It can also act as a buffering agent to help maintain a stable pH environment. Furthermore, sodium carbonate can be used to precipitate certain ions or compounds from solution.
What colour will sodium carbonate change pH paper?
Sodium carbonate is a basic compound, so it will turn pH paper blue in color.
Does sodium carbonate decrease or increase the pH of the wash water?
Sodium carbonate increases the pH of wash water. It acts as a buffering agent, helping to neutralize acids and raise the pH level.
What did the sodium carbonate do to the action of trypsin?
Sodium carbonate can increase the pH of a solution. In the case of trypsin, which functions optimally at a slightly basic pH, adding sodium carbonate can help maintain the enzyme's activity by providing the suitable pH conditions for its function.
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
What is the pH level in washing soda?
The pH level of washing soda, also known as sodium carbonate, is typically around pH 11 to 12. This high pH level makes it effective at breaking down grease and stains in laundry or cleaning applications.
