Is orange alkaline or acid?
Oranges are an acidic fruit due to their high vitamin C content. Vitamin C, also known as ascorbic acid, makes the pH of oranges distinctly acidic, meaning that if you’re trying to avoid acidic foods, eating an orange might not be the best idea.

- pomegranates (pH: 2.93–3.20)
- grapefruits (pH: 3.00–3.75)
- blueberries (pH: 3.12–3.33)
- pineapples (pH: 3.20–4.00)
- apples (pH: 3.30–4.00)

What is dispersed Orange used for?
Disperse Orange 1. Commercial samples contain approximately 25% dye by weight, with the remaining mass consisting of NaCl and other salts. This dye is useful in conducting experiments with flash photolysis due to the isomerization effect between the trans-4A4N and cis-4A4N states that occurs during photo relaxation.
What is disperse dye?
Disperse dye molecules are the smallest dye molecules among all dyes. A disperse dye molecule is based on an azobenzene (as Disperse Red 1 or Disperse Orange 37) or anthraquinone molecule with nitro, amine, hydroxyl, etc. groups attached to it. “Dyeing Polyester with Disperse Dye”. “Disperse Red 1”. “Disperse Orange 37”.
