1. Scope

1.1 These test methods cover the analyses usually required on commercial soda ash (sodium carbonate).

1.2 The analytical procedures appear in the following sections:

Sections Total Alkalinity, Titrimetric 8 to 15 Sodium Bicarbonate, Titrimetric 16 to 23 Loss on Heating, Gravimetric 24 to 30 Moisture, Calculation 31 to 35 Sodium Chloride, Titrimetric 36 to 42 Sodium Sulfate, Gravimetric 43 to 49 Iron, Photometric 50 to 58 Sieve Analysis 59 to 65

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 6.
