An oxide that turns red litmus paper blue when dissolved in water is typically a basic oxide, such as sodium oxide (Na2O) or potassium oxide (K2O). When these oxides dissolve in water, they form alkaline solutions, increasing the pH and causing the red litmus paper to change color to blue. This indicates the presence of a basic substance in the solution.
What else can I help you with?
What color does a base make litmus paper?
the red litmus paper turns to blue
What happens when sulphur dioxide dissolved in water is tested by blue litmus paper?
Burnt Magnesium ribbon ----> MgO (magnesium oxide)(basic in nature) When added to water, it forms its hydroxide MgO+H2O ----> Mg(OH)2 (which is a base) when added to litmus paper or litmus solution....it will give a light blue colour
What happens to red litmus paper if dipped in water?
Red litmus paper remains red when dipped in water. Litmus paper is used to test for acidity or basicity, and red litmus paper turns blue in basic solutions. If the water being tested is neither acidic nor basic, the red litmus paper will not change color.
What colour will litmus paper go when dipped in washing up liquid?
As soap is alkaline in nature, it turns red litmus paper blue
What color litmus paper is used to test acids?
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
An element x on burning in air forms an oxide which when dissolved in water turns blue litmus red idetify if x is metal or non - metal?
as blue litmus turns red the compound is an acid. Non metal oxides are acidic in nature. Thus the the element 'X' is a non metal.
When Litmus paper when added to calcium oxide and water?
When litmus paper is added to calcium oxide and water, it will turn blue due to the formation of calcium hydroxide, which is a basic solution. Calcium oxide reacts with water to form calcium hydroxide, releasing heat in the process.
How do you prove metal oxide is basic?
when ash of magnesium is dissolved in water then magnesium hydroxide is formed. MgO + H2O---->Mg{oh}2 hence, the solution is basic in nature.The oxides of metals are basic in nature.Therefore,their aqueous solution turns red litmus blue.
In a basic solution what color does litmus paper turn?
Litmus paper turns blue in basic solution.
What colour would litmus turn in acids?
blue litmus paper turns to red when its in contact with acid
What happens to red litmus paper when it touches a household cleaner that has ammonia?
Red litmus paper turns blue when it comes in contact with ammonia, which is a common property of bases. Ammonia creates a basic solution when dissolved in water, leading to the color change in the litmus paper from red to blue.
What color would the litmus paper turn if it was blue?
Blue litmus paper turns red in acid red litmus paper turns blue in alkali.
When litmus is placed in acidic solutions it turns what?
If it is blue litmus paper ,then it turns red. But if its red litmus paper, it doesn't change color.
Which litmus paper turns blue in acid solution?
Litmus paper is basically used to test nature of solution i.e acid or alkaline. For acid blue litmus turns to red. But for alkaline red litmus turns to blue color.
What color does hydrogen chloride turn damp litmus paper?
Hydrogen chloride turns damp blue litmus paper red.
A acid turns red litmus paper blue?
Blue litmus paper turns red under acidic conditions.
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.
