Baking soda reacts with the copper surface of the pennies, causing them to form a blue/greenish copper oxide layer. This chemical reaction changes the surface of the pennies, giving them a blue appearance.
The indicator with baking soda would likely turn blue or greenish-blue. Baking soda is basic, so it would cause the indicator to shift towards the blue end of the pH scale.
Litmus paper will turn blue when it comes into contact with a substance that is basic, such as baking soda.
Blue litmus paper will turn red when it comes into contact with an acidic substance like baking soda, indicating that the solution is acidic.
Red litmus paper will turn blue in the presence of baking soda, which indicates that the solution is basic.
If litmus paper is dipped in baking soda, it will turn blue. This is because baking soda is basic in nature and will cause the litmus paper to change color from red (indicating acidity) to blue (indicating basicity).
Litmus paper turns blue in the presence of a base like baking soda.
The indicator with baking soda would likely turn blue or greenish-blue. Baking soda is basic, so it would cause the indicator to shift towards the blue end of the pH scale.
Litmus paper will turn blue when it comes into contact with a substance that is basic, such as baking soda.
Blue litmus paper will turn red when it comes into contact with an acidic substance like baking soda, indicating that the solution is acidic.
I think you meant baking soda. Baking soda is basic, so red litmus paper will turn blue.
To a blue color.
Red litmus paper will turn blue in the presence of baking soda, which indicates that the solution is basic.
Blue. As bicarbonate is alkali
If litmus paper is dipped in baking soda, it will turn blue. This is because baking soda is basic in nature and will cause the litmus paper to change color from red (indicating acidity) to blue (indicating basicity).
Baking soda is a basic compound, so it would turn blue litmus paper red as it causes the paper to change color in the presence of a base.
The color become blue.
When red cabbage juice is mixed with baking soda, a chemical reaction occurs. The baking soda is a base and reacts with the anthocyanins in the red cabbage juice, causing a color change. The mixture will turn blue or blue-green due to the change in pH.
