Litmus is red at a pH under 4,5.
Purple litmus (neutral) become red in acidic solutions.
Sulphuric acid is mixed with copper oxide to make copper sulphate through a chemical reaction.
When salt (sodium chloride) is dissolved in water, it does not change the color of litmus paper. This is because salt is neutral and does not produce hydrogen ions (H⁺) or hydroxide ions (OH⁻) that would affect the acidity or alkalinity of the solution. Therefore, litmus paper will remain its original color, red for acid and blue for base, when in contact with a salt solution.
These acids doesn't react; they are only mixed.
There are very few naturally occurring liquids that are purple. One example is grape juice, which gets its purple color from anthocyanins found in grapes. Another example is some types of purple-colored cocktails or mixed drinks that may contain ingredients like blue curaçao or grenadine. Artificially colored beverages or drinks may also be purple, but these are typically not naturally purple.
Purple litmus (neutral) become red in acidic solutions.
Litmus paper will turn red in sulphuric acid.
Purple litmus paper will remain purple when dipped in tap water. Tap water is typically neutral or slightly basic, so it will not cause a color change in purple litmus paper.
It's purple the colour can change slightly. isn't that just great purple it's my favourite colour ya know
bright red / pink unless it kills the dye. I would try adding dilute amounts first. As a general rule Acids will turn litmus red / pink and bases will turn litmus blue / green
When blue and purple are mixed together, the color created is a shade of indigo.
When blue and purple are mixed together, the color produced is a shade of indigo.
When purple and blue are mixed together, the color produced is a shade of indigo.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
The resultant color of red mixed with blue is purple. Red and blue are primary colors that combine to create a secondary color, which is purple.
When purple and red are mixed together, the color created is a shade of maroon or burgundy.
