What plant dye can be used to detect acids and alkalis?
The most common is Litmus. Litmus is extracted from various Lichens and is a good indicator of both acids and alkalis. Some naturally occurring substances indicate only acids or alkalis such as cochineal and curcumin. The common litmus paper is impregnated with the dye extract of the Lichen to act as an acidity or alkalinity indicator. All PH (acidity and alkilinity) measuring devices work based upon whether they accept or donate protons and as such are infact themselves acids or bases. For greater accuracy other dyes (other than the reactive element) are added to the PH detector which can be chemically engineered to give visible changes in colour at every step on the PH scale.
What type of amino acids are all proteins are composed of?
Proteins are composed of 20 different amino acids. These amino acids can be classified into two main categories: essential amino acids, which must be obtained from the diet, and nonessential amino acids, which can be synthesized by the body.
What DNA belongs to the group of organic compounds known as?
The four major groups are carbohydrates, proteins, lipids and nucleic acid. Since DNA is made of nucleic acids on a sugar-phosphate backbone, its components would be in two categories, carbohydrates and nucleic acids.
What is made up of a chain of amino acids.?
PROTEIN is made up of chain of amino acids.
Are all enzymes made of fatty acids?
No, not all enzymes are made of fatty acids. Enzymes are primarily composed of proteins, which are made up of amino acids. Fatty acids are molecules that typically serve as a source of energy or as building blocks for other molecules in the body.
Are alkalis and acids dangerous?
Alkalis and acids can be dangerous if handled improperly. They can cause burns, irritation, and other harmful effects if they come into contact with skin, eyes, or other tissues. It is important to use appropriate precautions when working with alkalis and acids to prevent accidents and injuries.
What is made when acids react with alkalis?
When acids react with alkalis, they undergo a neutralization reaction to form salt and water. This process involves the transfer of protons from the acid to the alkali, resulting in the formation of a salt and water as the products.
Who were the first people to discover acids and alkali?
The concept of acids and alkalis has been known since ancient times. However, the first systematic investigation of acids and alkalis is often credited to the Ancient Greeks, notably Philosopher Thales of Miletus and Alchemist Jabir ibn Hayyan, who made important contributions to the understanding of these substances.
What hazmat is made up of acids and alkaline?
Corrosives are hazmat materials that contain acids and alkaline substances. These materials can cause severe burns to skin or eyes upon contact, and can pose a serious threat to health and the environment if not handled properly. Special precautions should be taken when storing, transporting, or disposing of corrosives to prevent accidents and exposure.
Are acids and and alkali made of hydrogen?
Acids contain hydrogen ions (H+), which are responsible for their acidic properties. Alkalis, on the other hand, are bases that contain hydroxide ions (OH-). Hydrogen is not the defining characteristic of alkaline substances.

What is soap a micture or a element?
Soap is a mixture composed of fatty acids, oils, and alkalis such as sodium hydroxide. It is not considered an element because it is made up of multiple different compounds.
What substance is made when alkalis react with oils and fats?
Soap
Why was Robert boules book on acids and alkalis important?
Robert Boyle's book on acids and alkalis, "The Sceptical Chymist," was important because it questioned traditional alchemical theories and laid the foundation for modern chemistry. Boyle proposed the idea that matter was made up of atoms and introduced the concept of chemical elements as distinct substances. His work helped to shift the focus of chemistry from mystical beliefs to empirical observations and experimentation.
Substance made when alkalis react with oils?
The process is called saponification, with which you make soap.
Is soap a acid neutral or base?
Soap is typically a base because it is made from fatty acids and alkalis such as sodium hydroxide. It works by reacting with oils and dirt on the skin to form soap molecules, which can then be rinsed away with water.
Is salt made by alkalis?
Yes, a reaction is: NaOH + HCl = NaCl + H2O
