How can you show that carbon dioxide is released during respiration?

Answer 1

the reason they say talking to plants helps them grow is because you breathe out the carbon dioxide when you breathe out.this is necisery (yes i miss spelled that) for photosynthesis, when plants make food. if this is a project conduct an expiriment with a plant you breathe on each day and another that you do not. the one you breathe on will show this.

Answer 2

Since carbon dioxide dissolves in water and forms carbonic acid, you could have water samples, one exposed only to the atmosphere, and one exposed to exhaled air, and then measure their pH with a pH meter.

Answer 3

The ever increasing rate of carbon dioxide and that being aside the fact that the oxygen that the plant makes during photosynthesis doesn't tip the balance of the amount of gases in the atmosphere. It is also proven by the fact that when we exhale, we exhale a gas. Scientific research has shown that aprt from water vspour, a little bit of oxygen and gases such as nitrogen and others, percentage of what you exhale is carbon dioxide.

Answer 4

To show that carbon dioxide is released during respiration, you can use a chemical indicator like bromothymol blue. When carbon dioxide is present, it reacts with water to form carbonic acid, which lowers the pH of the solution and changes the color of the indicator from blue to yellow. By adding this indicator to exhaled air or breath, you can observe the color change as evidence of carbon dioxide release during respiration.

Answer 5

By blowing into a test tube of bicarbonate of soda, this should turn cloudy if carbon dioxide is present

Answer 6

theoretically it would be easiest to use stoichiometry and balanced equations

Answer 7

you exhale air
