What is an acid and base?
An acid base indicator is a substance that changes colour due the PH of the medium in which it is dissolved.
A substance which ionizes to form hydrogen ions when dissolved in water is?
A substance which ionizes to form hydrogen ions when dissolved in water is called an acid. Acids turn blue litmus paper into red.
What substance must be present in the stomach for pepsin to work best?
Pepsin works best in an acidic environment, so the substance that must be present in the stomach for pepsin to work best is hydrochloric acid. This acid helps to activate pepsinogen into its active form, pepsin, which is responsible for breaking down proteins in the stomach.
What is the substance that contains hereditary material in living organisms?
The substance that contains hereditary material in living organisms is called DNA (deoxyribonucleic acid).
A base is a substance that forms hydrogen ions in a water solution?
This substance is an acid.
What substance neutralizes an acid?
A substance that neutralizes an acid is called a base. Bases can react with acids to form water and a salt, which helps to balance out the acidity.
What is the substance that neutralizes acid?
The substance that neutralizes acid is called a base. Bases work by accepting hydrogen ions from acids, which helps to balance out the pH level.
What is the substance that neutralises acid called?
Acid is neutralized by Bases (or Basic Substances.)
What is the substance that neutralizes sulfur?
The substance that neutralizes sulfur is called lime or calcium oxide.
What substance in pancreatic juice neutralizes the HCL?
Sodium bicarbonate is the substance in pancreatic juice that neutralizes hydrochloric acid (HCl) in the stomach. This helps create a more favorable pH environment for the enzymes in the small intestine to be effective in breaking down food molecules.
What is a acid in simple language?
a chemical substance that neutralizes alkalis, dissolves some metals and turns litmus red
What type of substance nutralises an acid?
An alkali substance typically neutralizes an acid. Alkalis are basic in nature and can react with acids to form salts and water, achieving a neutral pH.
Which substance neutralizes stomach acid as chyme enters the small intestine?
Bicarbonate is the secretion that neutralizes stomach acid as chyme enters the small intestine. Bicarbonate is necessary because chyme is highly acidic. Bicarbonate is created in the pancreas.
Define the heat of neutralization?
Heat of neutralization describes one of the effects of mixing a base with an equally strong acid. This neutralizes the substance, which changes the substance's heat as a result.
Is an antaacid medicine reacting with stomach acid a physical or chemical change?
The reaction of an antacid with stomach acid is a chemical change. The antacid neutralizes the acid, forming a salt and water, which is a new substance different from the original reactants.
Is neutralizes an acid chemical?
sodium bicarbonate.
A caustic absorbent neutralizes a spill by diluting it with acid?
A caustic absorbent is used to soak up the spill, while the acid neutralizes the caustic properties of the spill by reacting with it to form a less harmful substance. This reaction helps to make the spill safer for disposal and ensures it does not pose a threat to the environment or individuals.
