![]() ![]() If swallowed, medical help should be sought immediately. ![]() If calcium chloride comes in contact with skin, eyes, or clothing, it should be washed immediately with plenty of water. It is also important to avoid ingestion of calcium chloride, as it is toxic if consumed in large amounts.Ĭalcium chloride is corrosive to metal surfaces, so it must be used with care. It is important to wear proper personal protective equipment when handling calcium chlorides, such as gloves, a face mask, and glasses to protect the eyes. However, it can cause irritation to the skin and eyes and can irritate the throat if inhaled. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams. This gives a molar mass of 126.737 g/mol. It is also used in medical applications to treat certain health conditions. First, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). In general, calcium chloride is considered safe for intended uses, such as food processing, water treatment, and de-icing roads and pavements. Is Calcium Chloride SafeĬalcium chloride is POSSIBLY SAFE when used appropriately, but proper handling and precautions are important to avoid any potential risks or hazards. It is also important to use calcium chloride ice melt products according to their directions and to take proper safety precautions when handling and using the product. Additionally, calcium chloride helps reduce the time and effort required to clear snow and ice from surfaces, as it melts snow and ice more rapidly than other snow melters.Ĭalcium chloride tends to be more expensive than other snow melters, and it is also more corrosive to metal surfaces, requiring additional maintenance or repairs. And it lowers the freezing point of water, helping to melt ice and prevent further ice formation.Ĭompared to other common ice melting compounds such as sodium chloride (rock salt) and potassium chloride, it has a lower freezing point and can operate at lower temperatures. It is used to prevent ice from forming on roads, sidewalks, and other surfaces during the winter season. It is used in the treatment of low blood calcium levels (hypocalcemia) and as some medicines. It is used in various industries as a desiccant (drying agent) to remove moisture from the air.ĥ. It is used for water treatment plants to increase the hardness of the water.Ĥ. It is used as a food additive to enhance the firmness and texture of fruits and vegetables.ģ. It is used for de-icing and dust control.Ģ. Now, calcium chloride has a molar mass of approximately #"111 g mol"^(-1)#, which means that every mole of calcium chloride has a mass of #"111 g"#. So, Avogadro's number, which essentially acts as the definition of a mole, tells you that one mole of any ionic compound contains #6.022 * 10^(23)# formula units of that compound.Īs you can see, the sample given to you contains approximately half a mole of calcium chloride, since Once you know how many moles you have, you can use calcium chloride's molar mass to convert those to grams. Relative atomic mass of Ca 40.08 Relative atomic mass of Cl. ![]() What you need to do here is use Avogadro's number to calculate how many moles of calcium chloride, #"CaCl"_2#, are equivalent to that many formula units of this salt. CBSE Class 9 Answered CaCl2 molecule has one Calcium ( Ca ) atom and two chlorine ( Cl ) atoms.
