What else can I help you with?
What liquid turns pink when Sodium Bicarbonate is added?
phenolphthalein
What is the phenolphthalein color of baking soda?
Phenolphthalein is a pH indicator that turns pink in alkaline solutions with a pH greater than 8.2. Baking soda (sodium bicarbonate) is basic, so when phenolphthalein is added to a solution containing baking soda, it will turn pink.
What colour changes will appear when phenolphthalein is mixed with sodium chloride solution?
When phenolphthalein is mixed with sodium chloride solution, no color changes will occur. Phenolphthalein is a pH indicator that changes color in response to pH levels, while sodium chloride (table salt) does not significantly affect the pH of a solution.
How can one prepare a saturated sodium bicarbonate solution?
To prepare a saturated sodium bicarbonate solution, add sodium bicarbonate (baking soda) to water until no more can dissolve. This creates a solution where the maximum amount of sodium bicarbonate is dissolved in the water.
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 is the action of sodium bicarbonate in dakin's solution?
Sodium bicarbonate increases the antiseptic action of sodium hypochlorite.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.
Why does the indicator goes purple in sodium hydroxide solution?
The purple color in sodium hydroxide solution is an indicator of the presence of phenolphthalein, which turns pink in basic solutions. When phenolphthalein is added to sodium hydroxide solution, it reacts with the hydroxide ions in the solution to form the purple color.
Will bicarbonate lower pH?
Yes, because sodium bicarbonate solution is basic.
Is sodium bicarbonate (NaHCO3) soluble in water and therefore considered an aqueous solution?
Yes, sodium bicarbonate (NaHCO3) is soluble in water and forms an aqueous solution.
Is cholesterol soluble in sodium bicarbonate?
Cholesterol is not very soluble in sodium bicarbonate. However, in a basic solution, such as sodium bicarbonate, cholesterol forms some salts that are more soluble.
