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
When a metal powder is heated in open dish it turns black which metal is that?
The metal might be copper. When copper is heated, it reacts with oxygen in air forming copper oxide which is black in colour.
Is copper oxide a metal oxide?
Yes.
When metal reacts with oxygen what product is made?
[metal] oxide is the result. Iron oxide is called rust. Zinc oxide is called . . . zinc oxide which is a skin and wound soothing ointment.
Are oxide ores dissolved in acid solutions?
Yes, it is possible.
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?
If it forms an oxide, that litmus red , then it is an acidic oxide. Acidic oxides are formed from NON-Metals.
What colour does moist red litmus paper turn in magnesium oxide?
blue.
What experiment shows that sulphur forms an acidic oxide?
S+O2 gives rise to SO2. This is dissolved in water and tested with litmus paper.Red litmus turns blue which means it is acidic
What type of solution is formed when a non-metal oxide is dissolved in water?
Acid
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.
When sulfur is burned in air a gaseous oxide is formed If this gas is dissolved a sample of water containing litmus the result will be?
S + O2 --> SO2 SO2 + H2O --> H2SO4 H2SO4 is sulfuric acid and it will turn Blue litmus paper red.

What happens when red litmus paper is put into an acid?
It maintains its original hue. When placed in a base (metal oxide+water), it will turn blue.
Which metal oxide imparts black colour in glass?
Probable nickel or chromium oxides.
What color effervescense when sulfuric acid and copper oxide are mixed?
What is the colour of the solution formed when copper oxide is dissolved in dilute sulphuric acid? it turns blue!!!!!!!!!!!!!!!!!!!
A metal dissolved in water that can cause orange stains is what?
Iron most probably as it becomes iron oxide when placed in water.
Is CaO a metal oxide or non metal oxide?
Calcium is a metal, therefore this is a metal oxide.
