FAQs

What is HCl ACS reagent 37%? ›

Hydrochloric Acid 37% Solution, ACS Reagent Grade is is certified as the American Chemical Society (ACS) reagent due to its high level of purity and is acceptable for use in analytical applications and research laboratories. The 37% solution is the maximum attainable concentration of hydrogen chloride gas in water.

Signal Word: Danger Hazard Statement(s): Toxic if inhaled.

Applications: This grade of hydrochloric acid is used in metal processing, chemical manufacturing, and in the production of chlorides, fertilizers, and dyes.

A 37% w/w means that there are 37 grams of HCl in a 100 grams of solution. The molarity of the solution is. M o l a r i t y = m o l e s H C l L s o l u t i o n M o l a r i t y = 37 g 36.46 g / m o l e 100 g 1.18 g / m L M o l a r i t y = 1.01 m o l e 0.0847 L M o l a r i t y = 11.92 M.

Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-term) inhalation exposure may cause eye, nose, and respiratory tract irritation and inflammation and pulmonary edema in humans.

H314 Causes severe skin burns and eye damage. H335 May cause respiratory irritation. P260 Do not breathe dust/fume/gas/mist/vapours/spray. P280 Wear protective gloves/protective clothing/eye protection/face protection.

The abbreviation "A.C.S.," means the chemical meets the specifications of the American Chemical Society. A Certificate of Analysis is available upon request. • Guaranteed Reagent (GR) - Suitable for use in analytical chemistry, products meet or exceed American Chemical Society (ACS) requirements. where applicable. (

"ACS Reagent Grade", is regarded as a gold standard measure and is in some cases required for use in chemical manufacturing, usually where stringent quality specifications and a purity of equal to or greater than 95% are required.

How do you dilute 37 hydrochloric acid? ›

37% HCl means, 37- g of HCl is present in 100- ml of the solution. So 1000- ml of the solution will contain = 370- g of HCl. Therefore taking 4.93- ml of 37% of HCl and diluting it to 50- ml with distilled water (ie, adding 45.07- ml of distilled water to 4.93- ml of 37% HCl) we can obtain 50- ml of 1M HCl.

H2SO4, HCl and HNO3 are all strong acids, and dissociate completely in water at moderate concentrations. HCl is the strongest acid (indicated by the lowest pKa) followed by H2SO4 and HNO3. H3PO4 is the weakest of the acids.

Normality of 35% HCl= Mass/Eq. Mass =350/36.5= 9.589 N.

Hydrochloric acid is produced in solutions up to 38% HCl (concentrated grade). Higher concentrations up to just over 40% are chemically possible, but the evaporation rate is then so high that storage and handling require extra precautions, such as pressurization and cooling.

Hydrochloric Acid ACS Reagent Grade is meticulously crafted to meet the stringent standards of the American Chemical Society (ACS). This seal of approval signifies its suitability for the most sensitive analytical methods, where even minor impurities are intolerable.

37% HCl means, 37- g of HCl is present in 100- ml of the solution. So 1000- ml of the solution will contain = 370- g of HCl. Therefore taking 4.93- ml of 37% of HCl and diluting it to 50- ml with distilled water (ie, adding 45.07- ml of distilled water to 4.93- ml of 37% HCl) we can obtain 50- ml of 1M HCl.

Hydrochloric acid can be used to regulate the acidity (pH) of solutions. In industry demanding purity (food, pharmaceutical, drinking water), high-quality hydrochloric acid is used to control the pH of process water streams.
