The formation of copper(II) chloride during the reaction causes the blue-green color.

During the reaction, the solution undergoes a change in color, turning blue-green. This transformation occurs due to the formation of copper(II) chloride, which imparts the distinctive blue-green hue to the solution.

The described scenario depicts a neutralization reaction. This chemical process involves the combination of an acid and a base to produce a salt and water. In this specific case, the reaction results in the formation of copper(II) chloride, accompanied by ...

When metals react with acids, they displace hydrogen atoms to form hydrogen gas and a compound called a salt.

Olfactory indicators are useful in situations where visual observation of color changes may not be feasible or desirable. They can provide a quick and simple way to detect the presence of acids or bases, particularly in environments where chemical testing ...

Examples of substances acting as olfactory indicators include vinegar (acetic acid), which has a sour odor that becomes more pungent in acidic conditions, and ammonia, which has a strong, pungent odor that becomes more noticeable in basic conditions.

Olfactory indicators are substances whose odor changes in acidic or basic media. Unlike acid-base indicators, which change color, olfactory indicators rely on changes in smell to indicate the presence of acids or bases.

Acid-base indicators are commonly used to detect the presence of acids or bases in a solution by observing changes in color. They are valuable tools in laboratories and everyday applications for determining the pH of substances.

Besides litmus solution, name three other natural materials used as acid-base indicators.

When litmus solution is neither acidic nor basic, its color is purple.
