a)sulfur dioxide b)hydrogen chloride c)potassium sulfate d)slaked lime
soap is basic therfore, soap solution will keep blue litmus paper blue and turn red litmus paper blue
In acid solution, blue colour of litmus is changed into red. In basic sol litmus change to blue.
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.
It turns blue. Since chalk ( CaCo3) is a base and when pink litmus paper reacts with a base it turns blue
Red litmus paper is used to check for basicity. It turns blue when exposed to bases. Blue litmus paper is used to check for acidity. It turns red when exposed to acids.
Litmus paper turns blue when placed in basic solutions. This color change occurs due to a change in the pH level of the solution, causing the litmus paper to reflect the alkaline nature of the solution.
Litmus paper turns blue in basic solution.
detergent solution has an effect on red litmus paper because detergent solution is a base and it changes the color of red litmus(indicator) to blue when in contact with it.
So you can tell if the solution is an acid or a base
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.
Dilute HCl turns blue litmus paper red. This is because the HCl solution is acidic, causing a color change in the blue litmus paper indicating the presence of an acid.
Red litmus paper turn blue. But blue one is not responding.
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
Blue litmus paper will turn red in the presence of an acidic solution, while red litmus paper will turn blue in the presence of an alkaline (basic) solution.
Blue litmus paper turns red in an acidic solution.
A base.An alkali turns litmus paper blue.The solution is a base.
Blue litmus paper turns red in vinegar solution because vinegar is acidic and pH below 7. The acidic solution causes the blue litmus paper to undergo a color change and turn red.
