What else can I help you with?
Why are gas bubbles observed when the sodium bicarbonate is added?
with the reaction of acetic acid + sodium bicarbonate---->sodium acetate + h2co3 the product h2co3 is highly unstable which is eager to break down into its components of H2O and Co2 which is why gas bubbles are observed (its the CO2 that's formed in the process)
Why is adding vinegar to bicarbonate of soda a chemical change?
When vinegar (acetic acid) is added to bicarbonate of soda (sodium bicarbonate), a chemical reaction occurs that produces carbon dioxide gas, water, and sodium acetate. The formation of new substances with different properties is characteristic of a chemical change.
Why is sodium bicarbonate added to water?
Sodium bicarbonate is added to water to help regulate the pH levels and make the water less acidic.
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.
Is sodium bicarbonate a product or a reactant?
It depends. If sodium bicarbonate is added to something in a chemical reaction, then it is a reactant in this case. If a chemical reaction forms sodium bicarbonate, then it is a product.
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 NAHCO3 in H2O?
Na is sodium which has a charge of +1. This is your cation HCO3 is Hydrogen Carbonate which has a charge or -1. This is your anion. Thus your final answer would be Sodium Bicarbonate
What liquid turns pink when Sodium Bicarbonate is added?
phenolphthalein
How does the rate of photosynthesis change when sodium bicarbonate is added to the test tube?
the rate of photosynthesis increases as sodium bicarbonate is added to it as long as you stay proportionate to the amount of water in the test tube.
When sulphuric acid is added to sodium bicarbonate why does the colour change?
this makes sodium sulphate and CO2
How does the process of sodium bicarbonate dissociation occur in a solution?
When sodium bicarbonate is added to water, it breaks apart into ions, specifically sodium ions and bicarbonate ions. This dissociation happens because water molecules surround and pull apart the sodium bicarbonate molecules, causing them to separate into their individual components.
What will happen to the color of sodium bicarbonate if phenol red is add?
If phenol red is added to sodium bicarbonate, the color of the solution will change based on the pH. In an acidic solution, phenol red will appear yellow, in a neutral solution it will be red, and in an alkaline solution (such as when sodium bicarbonate is added), it will turn a pink or magenta color.
