What is the pH of flower?
depends what kind of flower xD
What other chemicals with high pH affect the color of flower petals?
none
What is special about hydrangea flowers grown in acid soil?
flower colour changes with pH
Why can ammonia change a flower's color through a flower's pigment?
ammonia can change the soils pH (acidity level) which can affect the formation of plant pigments or the absorption of elements
How does soil pH affect flower color?
Well, if the soil is acidic then the flower would turn and pink/red colour. if the soil had alkali then the colour would change to blue. Gardeners use this to make Hydrangeas change colour. other colours are possible to make, it all determines the Ph of the soil.
Does pH affect flower pigments?
It can. This is best illustrated by the hydrangea's flowers which are pink in alkaline soils and blue in acid soils.
Why does ammonia change a flower's color?
AnswerAmmonia diffuses readily through air and water, and since the petals of flowers are usually permeable to air and water, one can hypothesize that the ammonia can diffuse into the flower. Since ammonia is a base, its chemical pH reaction with the flower pigments could potentially cause flower color changes.
What plants can be used to make pH indicator?
If you are asking how to extract a chemical pH indicator from some plant type, I don't know. If you want to know a plant that indicates the relative pH of the soil it grows in, Hydrangea. Its flower's coloration is exactly like litmus paper's reaction to acids and alkalis.
Why have your blue agapanthus turned white?
Agapanthus colour is normally genetically determined, as such a white flower cannot turn blue. This does happen with flowers such as Hydrangea, where a blue or white flower can be turned pink - this is a result of the pH or acidity level of the soil
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 75?
PH 75 is the most acid.
When the soil pH is above 7.0 certain plants produce blue flowers. When the soil pH is below 7.0 however pink flowers are produced. What explains the color change?
The acid in the soil, this is only true with some flowers.-Purplicous: check out my bio page!!! Flower color change dependent on soil pH is true for only certain flowers. Hydrangea macrophylla is the most common plant that responds to soil pH by altering flower color. The color is dependent on the amount of available aluminum in the soil - more acidic soils (lower pH) allow the aluminum to be more accessible; more alkaline soils (higher pH) tie up the aluminum and it becomes less available. And the coloring is the reverse of that stated in the question! Lower pH generates BLUE flowers -- higher pH generates PINK flowers. Aluminum sulfate, aka "hydrangea bluing", is often used to acidify the soil and increase the aluminum availability to maintain blue hydrangea flowers. The effect is not immediate and be careful not to overapply - aluminum in excess can be toxic to many plants.
What solutions is the weakest acid pH of 2.4 pH of 5.2 pH of 6.4 pH of 8.6 or pH of 10.1?
pH=6,4
