The table below gives the density (kg/L) and the corresponding concentration (% weight) of Hydrochloric Acid (HCl) solutions in water at different temperatures in degrees centigrade (°C).
HCl Molar mass: 36.46 g/mol Appearance Colorless gas Odor: pungent; sharp and burning Density: 1.49 g/L [3] Melting point: −114.22 °C (−173.60 °F; 158.93 K) Boiling point: −85.05 °C (−121.09 °F; 188.10 K)
Physical properties of hydrochloric acid, such as boiling and melting points, density, and pH, depend on the concentration or molarity of HCl in the aqueous solution. They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl.
30 sty 2024 · The concentration denotes the mass concentration of the solution, expressed in units of density (usually g/l or g/ml). Molar mass is the mass of 1 mole of the solute. It is expressed in grams per mole. It is a constant property of each substance – for example, the molar mass of water is approximately equal to 18 g/mol.
“Concentrated” hydrochloric acid is an aqueous solution of 37.2% HCl that is commonly used as a laboratory reagent. The density of this solution is 1.19 g/mL. What mass of HCl is contained in 0.500 L of this solution? Solution. The HCl concentration is near 40%, so a 100-g portion of this solution would contain about 40 g of HCl.
Estimated values of absolute density (g/cm 3) of aqueous hydrochloric acid solutions {HCl + H 2 O) as function of electrolyte molality m and temperature T (at pressure p = 1 bar). Values in the table are consistent with the density of pure water calculated with the IAPWS-95 equation of state.
Hydrochloric acid density | Anton Paar Wiki. Description. Hydrochloric acid is an inorganic acid with the chemical formula HCl. It is classified as a strong acid and can attack the skin. It is a colorless liquid which has a distinctive, pungent smell.
