What else can I help you with?
How can you determine gasses present in solution using the expermints with BTB?
Bromothymol blue (BTB) can change color in the presence of carbon dioxide or acidic solutions, turning from blue to yellow. By observing the color change in a solution with BTB added, you can determine the presence of carbon dioxide or acidity levels, which can help identify certain gases like carbon dioxide in the solution.
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
Will strontium hydroxide react with carbon dioxide?
Strontium belongs to alkaline earth metalswhich form the stable carbonates so when carbon dioxide is added to aqueous solution of strontium hydroxide white ppts. of strontium carbonate are formed. Sr(OH)2+ CO2 = SrCO3 + H2O
What 2 solutions can be used to test for carbon dioxide?
lime water turns milky in the presence of CO2 Limewater (a solution of Calcium hydroxide) - when carbon dioxide is blown through the solution, a precipitate of Calcium carbonate is produced. The solution is said to turn "milky" or "cloudy". Bromothymol blue (pH range 2.4 to 4.6) (red in colour) is added to distilled water, which turns it yellow. Carbon dioxide turns the resulting yellow solution green.
What colour will limewater turn if carbon dioxide is added?
Limewater will turn milky white when carbon dioxide is added to it due to the formation of calcium carbonate.
When vinegar is added to some marble chips calcium carbonate what is the gas formed and how can it be identified?
When vinegar is added to marble chips (calcium carbonate), carbon dioxide gas is formed. This can be identified by observing bubbles forming in the solution during the reaction. The presence of carbon dioxide can also be confirmed by passing the gas through limewater, which will turn milky if carbon dioxide is present.
What is product when zinc added to carbon dioxide?
what is product when zinc added to carbon dioxide?
If an acid is added to an alkali the following is formed 1. carbon dioxide and water 2.salts and hydrogen 3.carbon dioxide and hydrogen 4.salts and water 5.oxygen and water?
a neutral solution is formed! (Acid + Alkali= salt+water)
When CaCo3 is added to Hcl what is formed?
Calcium chloride, Water, and Carbon Dioxide. Here is the BALANCED reaction equation. CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(g). NB When writing chemical formulae, please use the correct symbols. CaCo3 means one calcium atom and three(3) COBALT atoms. whereas I think you mean 'CaCO3' , which means 1 x (Ca)Calcium, 1 x (C)Carbon and 3 x (O)Oxygen. Similarly, Hcl means nothing. , whereas it should be written as 1 x (H)Hydrogen and 1 x (Cl)Chlorine. Note the use of CAPITAL letters for single letter elemental symbols and as the first letter for two letter elemental symbols. Please see the Periodic Table for the correct form of writing elemental symbols.
Which gas if formed when vinegar is added to calcium carbonate?
CO2- carbon dioxide
What colourless gas is produced when hydrochloric acid solution is added to sodium carbonate?
Carbon dioxide gas is produced when any strong acid is added to a metal carbonate.
What is produced when carbon dioxide is added to lime water?
When carbon dioxide is bubbled through it, they react together to form calcium carbonate (CaCO3) CO2 + Ca(OH)2 ---> CaCO3 + H2O This is the white precipitate
What would happen if you added zinc carbonate to sulfuric acids?
When zinc carbonate is added to sulfuric acid, a chemical reaction takes place where zinc sulfate, carbon dioxide, and water are formed. The zinc carbonate will dissolve in the sulfuric acid, releasing carbon dioxide gas and forming zinc sulfate solution. This reaction is a typical neutralization reaction between an acid and a base.
What is the white precipitate formed when carbon dioxide is added to lime water?
The white precipitate formed when carbon dioxide is added to lime water is calcium carbonate. This reaction occurs because the carbon dioxide reacts with the calcium hydroxide in the lime water to form calcium carbonate, which is insoluble and appears as a white solid.

Carbon dioxide is passed into a solution of bromthymol blue indicator until the acid solution turns yellow A sprig of elodea is placed into yellow solution and it turns blue purpose of experiment is?
The purpose of the experiment is to demonstrate the process of photosynthesis. When the elodea plant is added to the yellow solution (indicating acidity), it will consume carbon dioxide and release oxygen through photosynthesis. This will cause a color change in the solution from yellow to blue as the pH increases due to the removal of carbon dioxide.
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
