When a metal oxide is dissolved in water, it typically forms a basic solution. In this case, blue litmus paper will remain blue, indicating the basic nature of the solution. If the metal oxide were to produce an acidic solution, red litmus paper would turn blue, but this is less common for metal oxides.
What else can I help you with?
What oxide turns red litmus paper to blue when dissolved in water?
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 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 element oxide turned red litmus paper to blue?
A basic element oxide, such as sodium oxide (Na2O) or potassium oxide (K2O), can turn red litmus paper blue. These oxides react with water to form alkaline solutions, raising the pH and causing the color change in litmus paper. The shift from red to blue indicates the presence of a basic substance.
What element oxide turnuned red litmus paper to blue?
A basic oxide, such as sodium oxide (Na2O) or calcium oxide (CaO), can turn red litmus paper blue. This occurs because these oxides react with water to form alkaline solutions, which increase the pH and change the color of the litmus paper. Basic substances are characterized by their ability to accept protons or donate electron pairs in chemical reactions.
Metal combined with oxygen is?
metallic oxide
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.
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.
What oxide turns red litmus paper to blue when dissolved in water?
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.
Sodium is readily oxidized by oxygen gas if the product of the reaction were dissolved in water what would be the color the litmus for a litmus test?
The product of the reaction between sodium and oxygen is sodium oxide, which forms when sodium oxidizes in the presence of oxygen. Sodium oxide is a basic oxide and would turn red litmus paper blue, indicating it is basic.
What colour does moist red litmus paper turn in magnesium oxide?
Moist red litmus paper will turn blue when exposed to magnesium oxide because magnesium oxide is a basic compound. The red litmus paper will change color to blue to indicate the presence of a base.
When a non metal oxide is dissolved in water is the solution acidic or basic?
When a non-metal oxide, such as sulfur dioxide, is dissolved in water, it forms an acidic solution. This is because non-metal oxides react with water to produce acids.
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 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 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 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.
Is NO2 a metal or non-metal oxide?
NO2 is a non-metal oxide. Nitrogen dioxide (NO2) is composed of nitrogen and oxygen, both of which are non-metals on the periodic table. Non-metal oxides typically form acidic solutions when dissolved in water, as they react with water to produce acids. In contrast, metal oxides tend to form basic solutions when dissolved in water.
What does metal oxide and nonmetal oxide produces?
Metal oxides typically produce basic solutions when dissolved in water, while nonmetal oxides usually produce acidic solutions when dissolved in water. This is because metal oxides react with water to form hydroxide ions, increasing the pH, whereas nonmetal oxides react with water to form hydronium ions, decreasing the pH.
