Significance and Use:

Soda ash is used in a number of manufacturing processes. The procedures listed in 1.2 are suitable for specification acceptance and manufacturing control of commercial soda ash.

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, Titrimetric8-15
Sodium Bicarbonate, Titrimetric16-23
Loss on Heating, Gravimetric24-30
Moisture, Calculation31-35
Sodium Chloride, Titrimetric36-42
Sodium Sulfate, Gravimetric43-49
Iron, Photometric50-58
Sieve Analysis59-65

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 Review the current Materials Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, handling and safety precautions.

1.5 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.
