772 °C (anhydrous)
260 °C (monohydrate) 176 °C (dihydrate) 45.5 °C (tetrahydrate) 30 °C (hexahydrate)
NaCl melting point:
801 °C, 1074 K, 1474 °F
Calcium Chloride has a lower freezing point at -29 Deg F.
Sodium Chloride has a low limit of Approx -7De F
This couldn't be the right answer: these salts would have been molten to fluids at room temperature 68 oF !!
NaCl will affect them more than an equal gram amount of CaCl2.
The equations for freezing point depression and boiling point elevation are similar. For purposes of explanation we may look at the simplified equation for melting point depression.
ΔTF = KF · b · i
The question then is whether (moles of solute x van't Hoff factor) is greater for sodium chloride or calcium chloride.
The molecular mass of Sodium Chloride is 58.44 g/mol.
The molecular weight of Calcium Chloride is 110.984 g/mol.
From this we can calculate that
100 g of NaCl = 1.71 moles
100 g of CaCl2 = 0.90 moles
so for NaCl 1.71 x 2 = 3.42 and for CaCl2 0.90 x 3 = 2.70
Even though CaCl2 has a larger van't Hoff factor, its higher molecular weight means it would not depress the melting point as much as an equal weight of NaCl. The mathematics for boiling point elevation are analogous; an equal mass of NaCl will raise the boiling point more than CaCl2
Since calcium chloride is a solid (already frozen) at room temperature and methanol is a liquid at room temperature, methanol has a lower freezing point.
Sodium chloride doesn't contain calcium. Calcium chloride contain calcium.
Examples: sodium chloride, potassium chloride, sodium nitrate, calcium carbonate, calcium phosphate etc.
Examples are: sodium chloride, potassium chloride, calcium chloride, ammonium chloride, ammonium phosphates, sodium carbonate, sodium sulfate, magnesium sulfate, cooper sulfate, magnesium chloride.
Na (sodium), K (potassium), Cl (chloride), Mg (magnesium), Ca (calcium).
Calcium carbonate and sodium chloride are formed. CaCl2 + NaHCO3 = CaCO3 + 2 NaCl + H2) + CO2
The price is higher for the calcium chloride.
Pure sodium chloride doesn't contain calcium chloride.
The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.
Calcium carbonate and sodium chloride doesn't react.
Sodium chloride doesn't contain calcium. Calcium chloride contain calcium.
Sodium chloride doesn't contain calcium. Calcium chloride contain calcium.
Sodium chloride is NaCl, calcium chloride is CaCl2. Consequently all the physical and chemical properties are different.
Sodium chloride (NaCl) is a chemical compound. Calcium (Ca) is a chemical element.
Calcium carbonate (insoluble in water) is obtained and sodium chloride.
Calcium carbonate.
Sodium chloride is soluble in water, calcium stearate not.Put the mixture in water, stir and filter; sodium chloride remain in solution, calcium stearate on the filter.
It is not correct: calcium chloride is more efficient (but also more expensive); the cause is that the CaCl2 enthalpy of dissolution is higher.
