BS 976:1987

Based on International Critical Tables. Density in kg/m³ of aqueous solution, mass in g of HCl in 100 g of aqueous solution, mass in g of HCl in 1 litre aqueous solution. Notes on standard hydrometers, including corrections to be applied and worked examples.

This British Standard gives tables that enable the composition of an aqueous solution of hydrochloric acid to be determined from its density at temperatures between 0 °C and 40 °C.

Appendix A gives information on the corrections that are necessary when density is determined by a hydrometer complying with BS 718¹).

Appendix B gives information on the choice of BS hydrometers that are suitable for the determination of the density of hydrochloric acid solutions.

Appendix C gives examples of the use of a BS hydrometer in conjunction with Table 1.

NOTE The titles of the publications referred to in this standard are listed on inside back cover.
