Does sodium carbonate plus calcium chloride turn into milk??
What reaction occurs when sodium carbonate is mixed with calcium chloride?
This question takes us back to junior high school chemistry.
It is a very basic chemical reaction taught in junior high school, with the chemical equation:
The reaction produces a white precipitate of calcium carbonate.
Therefore, this reaction is also one of the important methods for synthesizing calcium carbonate.
It should be noted that sodium bicarbonate is a substance similar to sodium carbonate. Despite their similar names, sodium bicarbonate cannot react with calcium chloride to form a calcium carbonate precipitate.
Both in laboratory experiments and practical applications, it is necessary to confirm whether the raw material used is sodium carbonate.
Sodium carbonate, also known as soda ash, pure alkali or washing soda, has the chemical formula . Classified as a salt, it is a white powder easily soluble in water, which leads to the formation of precipitates in the reaction.
Its aqueous solution is weakly alkaline (capable of turning phenolphthalein solution pale red). It has a high solubility: 49.7 grams of sodium carbonate can dissolve in 100 grams of water (7.0 g at 0°C and 45.5 g at 100°C).
It is slightly soluble in absolute ethanol and insoluble in propanol.
It decomposes easily when heated.
Main Uses of Soda Ash
As a basic chemical raw material, sodium carbonate is widely used in industries including pharmaceuticals (for the treatment of excessive gastric acid in medical applications), papermaking, metallurgy, glassmaking, textiles and dyes. It is also used as a leavening agent in the food industry.
It is an indisputable fact that sodium carbonate reacts with calcium carbonate to form calcium carbonate. As we all know, calcium carbonate forms an off-white turbid liquid that looks extremely similar to milk. However, please do not consume calcium carbonate as if it were milk.
Weihai Haizhiyuan Chemical Co., Ltd. was founded in 2008, specializing in the production of salt chemical products. The company now owns complete production lines for products such as calcium chloride, magnesium chloride and industrial salt, and has passed the ISO9001 Quality Management System Certification.
Meanwhile, the company has established strategic cooperative relationships with large central state-owned enterprises including Sinopec Group, CNOOC Group and Shandong Haihua Group. It acts as an agent for their products such as soda ash and baking soda to achieve product diversification.
