Overview
Selenous acid protecting and changing the color of steel.
Applications
Selenous acid most commonly used as cold bluing process of steel. Mixture of selenous acid, copper(II) nitrate, and nitric acid changes the color of the steel from silver-grey to blue-grey or black. In place of copper nitrate and nitric acid BLUING process can be processed by use of copper sulfate and phosphoric acid with Selenious Acid.
Characteristics and notes
Mecke reagent is a mixture of selenous acid and concentrated sulfuric acid.
Mecke reagent is used as a simple spot-test to presumptively identify alkaloids as well as other compounds.
Testing procedure : Simply dripped Mecke Reagent onto the substance being tested, If the Substance contains any nitrogen item ALKALOIDS spot will be develope.
Mecke reagent can be produce by addition of 100 mL of concentrated (95–98%) sulfuric acid to 1 g of selenious acid.
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.

Potential Acute Health Effects: Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Hazardous in case of skin contact (permeator). Severe over-exposure can result in death. Inflammation of the eye is characterized by redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.
Potential Chronic Health Effects:
CARCINOGENIC EFFECTS: 3 (Not classifiable for human.) by IARC. MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. Mutagenic for bacteria and/or yeast. TERATOGENIC EFFECTS: Classified POSSIBLE for human.
DEVELOPMENTAL TOXICITY: Classified Reproductive system/toxin/female, Reproductive system/toxin/male [POSSIBLE].
The substance may be toxic to blood, kidneys, liver, skin, central nervous system (CNS). Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in one or many human organs.

Contact with skin |
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.. |
|
Contact with eyes |
Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately. |
|
Ingestion |
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention immediately. |
|
Inhalation |
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. |
|
Serious Inhalation |
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical attention. |

|
Environmental Precautions |
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. |
|
Small Spill |
Use appropriate tools to put the spilled solid in a convenient waste disposal container. |
|
Large Spill |
Poisonous solid. Stop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Call for assistance on disposal. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities. |
|
Precuation |
Keep locked up.. Do not ingest. Do not breathe dust. In case of insufficient ventilation, wear suitable respiratory equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes. |
|
Storage |
Keep container tightly closed. Keep container in a cool, well-ventilated area. Do not store above 25°C (77°F). |
