What colour does alkali turn in litmas paper?
Alkalis turn litmus paper blue. Litmus paper is used as an indicator to determine whether a substance is acidic or alkaline based on the color change it undergoes.
Alkalis turn paper blue?
Alkalis turn red litmus paper blue by converting the indicator dye to its basic form, which has a blue color. This color change occurs due to the increase in pH caused by the alkalis.
What is the correct scientific term for a substance that changes colour in this way for litmus?
indicator
If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
What is the change of colour of litmus paper when magnesium is burnt in air?
The litmus paper will turn red in the presence of magnesium oxide formed when magnesium is burnt in air. Magnesium reacts with oxygen to form magnesium oxide, which is a basic substance that turns red litmus paper blue.

What colour is litmus paper when it is alkalis?
Either baby blue(light blue), dark blue or dark purple. :)
What is a acid in simple language?
a chemical substance that neutralizes alkalis, dissolves some metals and turns litmus red
What is the purpose of an indicator in science?
An indicator usually means a substance which changes colour depending on what other substances are present. The most common type are acid/alkali indicators such as litmus, which is red in acids and blue in alkalis.
What is the correct scientific term for a substance that changes colour in this way for litmus?
indicator
What effect do alkalis hava on litmus solution?
If the solution contains acid, then the alkali turns the litmus to its original colour(blue).The color is effected by the concentration of the acid and the alkali.
If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
What colour will litmus paper go if dipped in acid substance?
red
What is the change of colour of litmus paper when magnesium is burnt in air?
The litmus paper will turn red in the presence of magnesium oxide formed when magnesium is burnt in air. Magnesium reacts with oxygen to form magnesium oxide, which is a basic substance that turns red litmus paper blue.
What are the changes to an indicator when acids and alkali are mixed?
When acids and alkalis are mixed, the pH of the solution changes. Indicators such as litmus paper will change color based on the new pH. Acids turn blue litmus paper red, while alkalis turn red litmus paper blue.
