Increases as the acid donates H+ ions to react with the base to form water, resulting in an increase in the concentration of OH- ions in the solution.
is soluble in water and will fizz when hydrochloric acid is added
You should always add (small parts of) the concentrated compound (acid, hydroxide) to (the larger amount of) water, because you can stirr and mix and cool down better (heat of hydration can be absorbed much better by the water and surroundings)
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.
The acidity of the liquid in the beaker likely changed due to the addition of an acid or a base, which would alter its pH level. If an acid was added, the pH would decrease, indicating increased acidity. Conversely, if a base was added, the pH would increase, resulting in decreased acidity. Additionally, factors such as temperature or dilution could also affect the acidity of the solution.
The material in the acidic beaker should have a lower pH compared to the material in the basic beaker before any acid or base is added. This is because the acidic beaker contains an excess of hydrogen ions, resulting in a lower pH, while the basic beaker contains an excess of hydroxide ions, leading to a higher pH.
The pH drops. The stronger the acid the lower the pH.
When sodium hydroxide solution is added to hydrochloric acid in a beaker, a chemical reaction occurs, resulting in the formation of water and sodium chloride salt. This reaction is exothermic, meaning it releases heat energy. The pH of the resulting solution will increase due to the presence of sodium hydroxide, which is a strong base.
If hydrochloric acid is added to a beaker, the salt formed will depend on the other reactant present. For example, if sodium hydroxide is also present, sodium chloride (table salt) will be formed. The specific salt formed will depend on the combination of the acid and base used in the reaction.
To dilute sulfuric acid safely, always add the acid to water slowly while stirring constantly. Never add water to the acid as this can cause splattering. Use appropriate protective gear such as gloves, goggles, and a lab coat when handling sulfuric acid.
Increases as the acid donates H+ ions to react with the base to form water, resulting in an increase in the concentration of OH- ions in the solution.
When dilute hydrochloric acid is added to copper oxide in a beaker, a chemical reaction occurs where the acid reacts with the oxide to form copper chloride, water, and releases carbon dioxide gas. This reaction will be observed as bubbling or fizzing due to the release of the gas. The color of the solution may change as well, from blue-green to a light blue due to the formation of copper chloride.

The pH of water will decrease when hydrochloric acid, a strong acid, is added to it. This is because the strong acid will increase the concentration of hydrogen ions in the water, leading to a lower pH.
