What color does francium turn when it burns?
Francium does not exist in large enough quantities to be studied directly. However, if it were to burn, it would likely produce a pale yellow flame due to the characteristic color of the alkali metals when they burn.
What color will a flame turn if a ghost is near?
Blue
What color do blueberries turn in an Alkali solution?
Blueberries turn green in an alkali solution due to a change in the pigment molecules. The anthocyanin pigments in blueberries react with the alkaline pH, causing the color change.
What color is the flame of Strontium nitrate?
The flame of strontium nitrate is red. It produces a bright red color when ignited.
What alkali metal produces violet flame when mixed with water?
Lithium is the alkali metal that produces a violet flame when mixed with water. This color arises due to the excitation of electrons in the lithium atoms, leading to the emission of light in the violet part of the spectrum.
What colour will universal indicator turn when acid is mixed with alkali?
Universal indicator will turn green when an acid is mixed with an alkali. This green color indicates a neutral pH level which is achieved when the acid and alkali have neutralized each other.
What color does sulfur turn a flame with oxygen?
Sulfur burns with a blue flame when it reacts with oxygen.
What is colour of universal indicator be in weak alkali?
In weak alkali, universal indicator will typically turn green or blue. The specific color will depend on the pH of the solution - the higher the pH, the bluer the color.
What colour does blackcurrant juice turn in an alkali?
Blackcurrant juice turns a bluish-black color in an alkali due to the presence of anthocyanins, which are pigments that change color based on pH levels.
What color does Iron (III) chloride turn in flame test?
Iron (III) chloride does not produce a distinct color flame during a flame test. This compound is typically used more for other chemical tests rather than flame tests for cation identification.
What is the major difference between the colours of flames produced by alkali metal with that of calcium when performing flame tests?
The major difference is the color of the flame produced. Alkali metals typically produce a lilac or purple flame, while calcium produces an orange-red flame. This difference is due to the unique electronic configurations and energy levels of the atoms in each element.
What color does onion skin turn in acid and alkali?
Onion skin turns red in acid and green in alkali due to the presence of anthocyanin pigments that change color based on the pH of the solution.
