The gas that turns a universal indicator blue is usually chlorine.
What else can I help you with?
What colour does hydrogen turn moist universal indicator paper?
the formale name for it is scarlet but it means bright red
What colour does magnesium turn added with water and universal indicator?
When magnesium is added to water with universal indicator, the indicator may initially turn blue (indicating a basic solution due to the formation of magnesium hydroxide) before turning back to its original color as the magnesium metal reacts with water to form magnesium hydroxide and hydrogen gas.
What is the colour with universal indicator smelling salts?
The color of universal indicator in smelling salts can vary depending on the specific chemical composition and pH of the salts. However, typically smelling salts with universal indicator will change color to indicate the presence of ammonia gas, which is often associated with a blue or green color change in the indicator solution.
What is a chemical indicator for carbon dioxide?
Bromothymol blue is a chemical indicator that can be used to detect the presence of carbon dioxide. In the presence of carbon dioxide, the indicator changes color from blue to yellow. This change in color indicates the presence of carbon dioxide gas.
Which gas turns moist starch iodide paper blue black?
Chlorine gas turns moist starch iodide paper blue-black.
What colour would ammonia gas turn universal indicator paper?
Ammonia gas would turn universal indicator paper blue or purple depending on the concentration of ammonia present.
What colour does hydrogen turn moist universal indicator paper?
the formale name for it is scarlet but it means bright red
What colour does magnesium turn added with water and universal indicator?
When magnesium is added to water with universal indicator, the indicator may initially turn blue (indicating a basic solution due to the formation of magnesium hydroxide) before turning back to its original color as the magnesium metal reacts with water to form magnesium hydroxide and hydrogen gas.
What effect does chlorine have on moist universal indicator?
Chlorine turns moist universal indicator paper red, then bleached. It has the same effect on blue litmus paper (red then bleached). this shows it is an acidic gas and so when reacts with sodium for example (an alkali metal) makes sodium chloride (salt).
What is the colour with universal indicator smelling salts?
The color of universal indicator in smelling salts can vary depending on the specific chemical composition and pH of the salts. However, typically smelling salts with universal indicator will change color to indicate the presence of ammonia gas, which is often associated with a blue or green color change in the indicator solution.
What is a chemical indicator for carbon dioxide?
Bromothymol blue is a chemical indicator that can be used to detect the presence of carbon dioxide. In the presence of carbon dioxide, the indicator changes color from blue to yellow. This change in color indicates the presence of carbon dioxide gas.
What happens if methylene indicator strip turns blue inside the Gas Pak jar?
If the methylene blue indicator strip turns blue inside the Gas Pak jar, it indicates that there is oxygen present in the jar. This could mean that the anaerobic conditions inside the jar have been compromised, and the contents may be exposed to oxygen, potentially affecting the growth of anaerobic organisms inside the jar.
How do you figure out ammonia gas by doing a test?
In the presence of hydrogen chloride a white smoke is formed; also ammonia turn an universal indicator paper to blue.
When you add an acid to a carbonate to a universal indicator it turns milky?
This is false. When you add a carbonate to universal indicator it's does not turn milky. In actual fact it turns either like thick bubbly layers or stay the same depending on the acid type are using in this situation. Because of chemistry scientists have sussed that there is no acid which can make the universal indicator turn milky. So the answer to the question is no and if you have to put this question into into a trye or false table then this question would go under FALSE because it does not turn milky.
Does universal indicator turn milky when acid is added to a carbonate?
Yes, when acid is added to a carbonate, it reacts to produce carbon dioxide gas. This gas can create a milky appearance in universal indicator due to the production of tiny gas bubbles that scatter light.
Which gas turns moist starch iodide paper blue black?
Chlorine gas turns moist starch iodide paper blue-black.
What happens when sodium is added to water and universal indicator?
When sodium is added to water, it reacts vigorously, releasing hydrogen gas and forming sodium hydroxide. The solution will become alkaline due to the formation of sodium hydroxide. When universal indicator is added, it will change color to indicate a high pH level, typically turning purple or blue for strong alkaline solutions.
