What gas is present in exhaled?
carbon dioxide
When mixed with a drop of bromthymol blue what will cause the indicator to turn from blue to yellow?
Bromthymol Blue indicates Carbon dioxide is present. It is also a general acid-base indicator. When it turns green it is at the endpoint of the titration. When it turns yellow, it is overshot and thus acidic.
Color of phenolphthalein plus NaOH?
Phenolphthlalein is something like a pH indicator. When it is added to a liquid and the liquid turns pink, it means that the latter substance is basic.When the solution is added with NaOH, it will turn pink.Note that NaOH serves as a carbon dioxide neutralizer.The color of the solution will slowly fade after some time, because carbon dioxide is present in the air neutralizing the color effect of the NaOH.
Which gas molecule containing three atoms present in dry air?
Carbon dioxide CO2 is usually the main triatomic gas present in dry air. Sulfur dioxide, SO2 is also present in many locations.
What is the purpose of adding an indicator to an unknown solution?
Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
How does carbon dioxide change the acid-base condition when present in excess?
Carbon dioxide makes conditions more acidic. If moisture is present carbonic acid will form.
What test could you use to find out if CO2 gas is present in a small container?
Blow it through limewater. If the limewater turns "milky" or "cloudy" (a white substance is shown) then Carbon Dioxide is present. If nothing happens, then Carbon Dioxide is not present in your solution.
Why freshly prepared 'KOH' solution is taken in a watch-glass and kept in the bell jar during the experiment to show that carbon-dioxide is essential for photosynthesis?
It is because 'KOH' solution helps to absorb all the carbon dioxide present in the bell jar.
Why does lime water turn chalky when cardon dioxide is present?
The carbon dioxide forms a precipitate with the calcium hydroxide. (Lime water is just a solution of calcium hydroxide) This precipiate is what makes it look chalky
What substance used to detect the presence of carbon dioxide?
Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
What is its present condition?
The condition it is in now.
What is the function of lime water used in testing for carbon dioxide gas?
It is to make sure that carbon dioxide is present or not present in the experiment.
How can we prove that carbon dioxide is present in the air?
A candle dye out in carbon dioxide.
Why is carbon dioxide present in the air?
Carbon dioxide is present in the air because plants need carbon dioxide to make food and without carbon dioxide plants would die and eventually the rest of the food chain.
Why is not proper the gaseous state of carbon dioxide as vapor?
It is not proper to say "Vapour is a proper name for the gaseous state of carbon dioxide" because carbon dioxide is not present as liquid under natural circumstances. The gaseous state of a substance ABOVE its own fluid (or dissolved in a solution) is called vapour of that particular compound.
What is the test for carbon dioxide?
to test for carbon dioxide is already dissolved in limewater , after this shake up the test tube , is it be that carbondioxide is present then two things will happen : 1) the limewater will turn cloudy as co2 is a precipatate is this solution 2)the limewater will begin to show efferevescence now we know gas is present if these two thing happen then there is an extremly high chance that co2 is present.
Is there naturally sulfur dioxide in water?
No sulfur dioxide is not present naturally. It pollutes the water.
