A substance that lowers hydrogen ion concentration (H⁺) and decreases pH when it dissociates in water is an acid. When an acid, such as hydrochloric acid (HCl), dissociates in water, it releases H⁺ ions, increasing the acidity of the solution and resulting in a lower pH. This process is fundamental to understanding acid-base chemistry.

What is a substance that increases H and decreases pH when it dissociates in water?

An acid is a substance that increases the concentration of hydrogen ions (H+) and decreases the pH when it dissociates in water. Examples of acids include hydrochloric acid (HCl) and acetic acid (CH3COOH).


What is acidity of substances?

Acid is a substance that, when added to water, dissociates (dissolves) to release H+ ions into the water. The higher percent of the acid that dissociates, the stronger the acid.


Why does temperature of water lowers on adding glucose?

It will increase the surface tension of water hence temperature decreases. If you add phenol to water temperature increase as it decreases the surface tension.


What substance produced by the body lowers the surface tension of water?

Bile


What substance can be used to electrolyze water?

A common substance used to electrolyze water is a salt, such as sodium chloride. When salt is dissolved in water, it dissociates into sodium and chloride ions, which can then conduct electricity to facilitate the electrolysis of water.


What is a substance that ionizes or dissociates into ions when placed in water?

every gas can be ionised, in fact, any chemical can be ionised.


If a substance dissociates and forms an excess of h positive ions when dissolved in watr it is referred to as?

If a substance dissociates and forms an excess of H+ ions when dissolved in water, it is referred to as an acid. Acids are substances that donate protons when dissolved in water, leading to an increase in H+ ions concentration in the solution.


What makes a substance a strong electrolyte?

A substance is considered a strong electrolyte if it completely dissociates into ions when dissolved in water, allowing for a high conductivity of electric current.


An inorganic compound when placed in water dissociates 99 percent forming hydrogen ions and anions what would this substance be?

This substance would likely be a strong acid, such as hydrochloric acid (HCl) or sulfuric acid (H2SO4), which dissociates almost completely in water to form hydrogen ions (H+) and anions.


What is a base in a scientific phrase?

In chemistry a base is a substance that is a water-soluble compound capable of reacting with an acid to form a salt and water. An Arrhenius base is a substance that dissociates in aqueous solution to produce hydroxide ions (OH-).


What is Any substance that forms hydroxide ions in a water solution is a?

it is electrolyte, probly to late now but, yeah.


How can you determine if a substance is a strong acid?

A strong acid is a substance that completely dissociates in water to produce a high concentration of hydrogen ions. You can determine if a substance is a strong acid by testing its ability to fully ionize in water and produce a low pH level below 7.
