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 happens to the pH of an acid when an acid is added?
when acid is added to a substance in the pH, the substance rises in a pressurized state
When water is added to a strong acid or base the acid or base becomes less dilute?
When water is added to a strong acid or base, the concentration of the acid or base decreases because water dilutes the solution. This results in a less concentrated solution of the acid or base.
Which substance should be added first when mixing acid and water?
When mixing acid and water, always add the acid to the water slowly and carefully. Never add water to acid, as it can cause a dangerous reaction.
What happens to pH of water when hydrochloric acid is added to water?
The pH of water decreases when hydrochloric acid is added to it because hydrochloric acid is a strong acid that donates protons in water, increasing the concentration of hydrogen ions and lowering the pH of the solution.

What substance is soluble in water and will hissing when hydrochloric acid is added?
is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added

When water is added to a strong acid or base, the concentration of the acid or base decreases because water dilutes the solution. This results in a less concentrated solution of the acid or base.
What is a substance that lowers H and decreases pH when it dissociates in water?
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 substance is added water that increases a hydronium?
An acid, such as hydrochloric acid (HCl) or sulfuric acid (H2SO4), is added to water to increase the concentration of hydronium ions (H3O+). This process is known as acidification.
Which substance should be added first when mixing acid and water?
When mixing acid and water, always add the acid to the water slowly and carefully. Never add water to acid, as it can cause a dangerous reaction.
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.
What happens to pH of water when hydrochloric acid is added to water?
The pH of water decreases when hydrochloric acid is added to it because hydrochloric acid is a strong acid that donates protons in water, increasing the concentration of hydrogen ions and lowering the pH of the solution.
What substance that's added to acid has no visible change?
When an acid is mixed with water, there is usually no visible change, but the acid becomes less concentrated.
What happens when acidic substances are added to water?
When an acidic substance is added to water, it forms an acid. Examples of this kind of chemical reaction include: Sulfur Dioxide + Water --> Sulfurous Acid SO2 + H2O --> H2SO3
What is an arrhensius acid?
An Arrhenius acid is a substance that when added to water increases the concentration of H+ ions. When it is added to water, it loses its hydrogen ion, which combines with water molecules to form hydronium, H3O+. Hydrochloric acid is an example of an Arrhenius acid. HCl + H2O ---> H3O+ + Cl-
