What happens when dilute hydrochloric acid reacts with calcium carbonate?

Calcium carbonate reacts with hydrochloric acid to produce calcium chloride ,water and carbon dioxide gas.

What precautions must be taken when working with hydrochloric acid?

Handling. Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood.

What are two hazards of concentrated hydrochloric acid?

Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-term) inhalation exposure may cause eye, nose, and respiratory tract irritation and inflammation and pulmonary edema in humans.

What are the five types of safety hazards found in the laboratory?

To generate awareness and offer safeguards for laboratory workers, Workrite Uniform Co. has created a Top 5 list of laboratory hazards.

• Fire/Explosions.
• Thermal and Chemical Burns.
• Skin Absorption of Chemicals.
• Inhalation of Toxic Fumes.
• Cuts to the Skin.

What are some safety precaution in handling acids and bases?

Personal protective equipment:

• Face protection, such as a face shield, is required when working with large volumes of liquid acids and bases.
• An apron or disposable gown must be worn when working with large volumes of liquid acids and bases.
• Acid-resistant gloves must be worn when handling acids and bases.

Why is hydrochloric acid hazardous?

Hydrochloric acid is a hazardous liquid which must be used with care. The acid itself is corrosive, and concentrated forms release acidic mists that are also dangerous. If the acid or mist come into contact with the skin, eyes, or internal organs, the damage can be irreversible or even fatal in severe cases.

How does carbonate react with dilute acid?

Acids react with metal carbonates or metal bicarbonates to give out carbon dioxide, along with the corresponding metal salts and water. Sodium carbonate reacts with hydrochloric acid to form sodium chloride, carbon dioxide, and water. This carbon dioxide gas is allowed to pass through lime water, turning it milky.

What are the most common laboratory safety problem?

Storage of chemicals and equipment inside the fume hood. Storage of flammable chemicals inside refrigerator which is not fire-proof. Touching door handles with contaminated gloves. Walking outside the LABs with contaminated LAB coats and gloves.

What happens when you mix hydrochloric acid and calcium carbonate?

Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas. One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.

What happens when metal carbonate reacts with dilute acid?

Metal carbonate compounds react with dilute acids and emit carbon dioxide gas. Calcium carbonate is not soluble in water and exists as white precipitate in the water. When aqueous hydrochloric acid is added, calcium chloride, carbon dioxide and water are formed. Calcium chloride (CaCl 2) is soluble in water and colorless.

What happens when CaCO3 reacts with 2HCL and CO2?

CaCO 3 (s) + 2HCl (aq) → CaCl 2 (aq) + CO 2 (g) + H 2 O (l) What happens when CaCO 3 reacts with dilute HCl acid? Calcium carbonate reacts with dilute acids to produce a calcium salt, water and carbon dioxide gas: calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxide.

How does surface area affect the rate of reaction of calcium carbonate?

My hypothesis was that if the surface area to volume ratio of calcium carbonate was increased, then the rate of the reaction will increase because there are more particles that are accessible by the hydrochloric acid, thus more particles that can react with each other.
