What happens when you mix sodium bicarbonate solution and phenolphthalein?
it turns into a pinkish red color
What is the colour of bicarbonate of soda added to universal indicator?
When bicarbonate of soda is added to universal indicator, it typically turns the solution a blue or purple color. This indicates a basic pH level.
What happens when calcium chloride sodium bicarbonate and phenol red solution are mixed together?
Calcium Chloride and Sodium Bicarbonate turn pink, then turn yellow due to carbonic acid that is created. the mixture turns hot and gas is, about 10 seconds later the mixture stops producing gas and turns cold.
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.
Is sodium bicarbonate insoluble in acetone?
salicylic acid is non polar and will not dissolve in water. However, it is soluble in sodium bicarbonate solution because an acid-base reaction occurs. Salicylic acid turns to a salt called sodium salicylate. Sodium salicylate is composed of a cat ion (Na+) and of an anion (salicylate ion). Because of the negative charge in the salicylate ion and the positive charge of Na+, water molecules in the sodium bicarbonate solution and from the reaction are attracted to these ions and eventually dissolve them.
What happens to the indicator when hydrochloric acid is added to sodium hydroxide?
It turns from its original blue colour to red.
Are boiling and melting the same?
No boiling is heating and energy is added and melting the solid turns into a liquid.
What is it call when liquid water turns to liquid vapor?
When liquid water turns into liquid vapor, it is called evaporation. This process occurs when heat energy is added to the liquid water, causing molecules at the surface to gain enough energy to escape into the air as vapor.
When a cold temperature is added to a liquid it turns to gas?
First you can not add a cold temperature to anything. Ask your teacher to explain what heat is an what temperature is, because you clearly do not understand this. When a liquid BOILS - it turns into gas. When a liquid FREEZES - it turn into a solid.
What happens if you put heaps of energy (heat) into a liquid?
The liquid's temperature will increase. If enough heat is added, it will eventually evaporate.
When heat is added to or removed from a substance it may change its state. What state will most likely result if heat is added to a liquid?
In that case, the liquid may eventually change to a gas.
What color does bicarbonate indicator turn?
The bicarbonate indicator turns from purple to yellow when exposed to a basic solution.
