a)sulfur dioxide b)hydrogen chloride c)potassium sulfate d)slaked lime
Water and neutralized salts have no effect on litmus paper because they are neither acidic or basic.
A neutral solution
For example nitrogen and argon.
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.
Red litmus paper turns blue in a basic solution. There is no effect on blue litmus paper.
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.
Litmus paper turns blue in basic solution.
Draino turns litmus paper blue.
So you can tell if the solution is an acid or a base
Blue litmus paper turns into red.
it is litmus not lithmus . it is a natural indicator . it is a strip of paper either red or blue in colour . it is used whether a solution is acidic or basic in nature. a basic solution turns red litmus to blue and an acidic solution turns blue litmus into red
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
An acid solution turns blue litmus red.
blue
Dip the litmus paper into the solution you are testing. Hold it up in the air, holding the dry bit. Look at the bit you dipped. If the solution was an acid, red litmus will stay red, blue litmus will turn red. If the solution was an alkali, red litmus will turn blue, blue litmus will stay red. If the solution was neutral, red litmus will stay red, blue litmus will stay blue.
blue litmus remains blue while red litmus changes to blue
