By using cobalt chloride paper. The acidity of the water would change the color of the paper due to the Ph balance.

How do sharks detect the presence of food?
When they can smell blood in the water.
How can you detect the presence of water vapour?
One common method to detect the presence of water vapor is to use a hygrometer, which measures the humidity levels in the air. Another method is using a dew point thermometer, which measures the temperature at which air becomes saturated and condensation forms. Additionally, specialized instruments such as moisture meters can also be used for accurate detection of water vapor content in various materials.
What does emulsion test detect?
The emulsion test is used to detect the presence of lipids (fats) in a substance. It involves mixing the test substance with ethanol and water to form an emulsion. The presence of a white emulsion indicates the presence of lipids.
How do you prove that water vapour is present in the air by using only a beaker and several ice cubes?
Place the ice cubes in the beaker and wait for a few minutes. If water droplets form on the outside of the beaker, it indicates that water vapor in the air has condensed on the cold surface of the beaker. This condensation process proves the presence of water vapor in the air.
How do you detect water vapour in the air?

What test can be used to detect substance of emulsion?
A drop test can be used to detect the presence of an emulsion. Add a drop of the emulsion to water. If it disperses or forms a milky appearance, it indicates the presence of an emulsion.
Can water vapor rust iron?
Rusting will only occur in the presence of both water and oxygen. In the presence of oxygen, water vapour in the air will cause rusting to occur. So unless you are talking about the iron coming into contact with water vapour but when there is no oxygen, the answer is yes.
How do you watch weather from space?
There are weather sattellites that orbit the Earth that can detect reflected radiation, emitted radiation, or radiation reflected only by water vapour as well as satellites that emit microwave radiation to detect the clouds or precipitation.
Why is it necessary to make periodic chemical and bacteriological analysis of water used for drinking?
To detect the presence of poisionous elements such as lead and to detect if there is contamination of the water source of harmful bacteria such as E Coli
What is water turned into gas called?
It is called water vapour or simply vapour.
what is the molecular mass of water vapour?
The molecular mass of water vapour is 18.01528
Why can you see clouds but not water vapour in the air?
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
