base
Acid-dark pink(magenta) base-green neutral-colourless
Bases turn pink when dipped in china rose solution due to the formation of a complex ion between the base and the indicator. This color change is a result of the pH change caused by the addition of the base.
if you put a china rose into a solution: if it curls up (the edge of the china rose) THEN ITS AN ACID if it remains flat: its a base. [[before you would use a china rose as an indicator, you want to flatten it until it remains flat. Thus, when you purchase a china rose, of course the petals are curly/wavy]] Thus, i just made all this up n_n. Have a nice day;)
When acid is added to china rose solution the color changes into deep pink.
In acid: colorless8.2 purple]In base: purple
When acid is put on china rose indicator, the indicator will turn red in color. This color change indicates that the solution is acidic. China rose indicator contains anthocyanin pigments that change color based on the pH of the solution.
Acidic conditions can cause china rose petals to lose their color or wilt more quickly because acids can disrupt the natural pH balance of the petals. It's best to avoid exposing china rose petals to acidic substances to maintain their appearance and freshness.
The color of rose petal becomes white from pink under the influence of citric acid
Kaolin is found in bone china and it is a base. Al₂Si₂O₅(OH)₄
When soap solution is mixed with china rose solution, the soap molecules disrupt the surface tension of the water. This leads to the formation of bubbles and foam as the soap molecules surround the pigments in the china rose solution, causing them to become trapped in the bubbles. The interaction between the soap and china rose solution demonstrates the ability of soap to emulsify and suspend particles in water.
Hibiscus flower petals are commonly used as an acid-base indicator. In acidic conditions, the petals turn red, while in basic conditions, they turn blue or green. This color change is due to the presence of natural pigment compounds in the flower petals called anthocyanins.
