Guar gum Ganganagar and Hanumangarh in Rajasthan are the major Guar trading markets. The United States has produced 4,600 to 14,000 tonnes of guar over the last 5 years. Texas acreage since 1999 has fluctuated from about 7,000 to 50,000 acres. The world production for guar gum and its derivatives is about 1.0 Million tonnes. Non-food guar gum accounts for about 40% of the total demand. Mainly it is used as a proppant transport / proppant suspending agent in hydraulic fracturing. At its peak the price was $8000 per ton. Chemically, guar gum is an exo-polysaccharide composed of the sugars galactose and
Hydrochloric acid at 180°). The author suggests that HO may become more important in dilute HCl solutions. ("See" hydronium ion "for further discussion of this issue.") Hydrochloric acid is a strong acid, since it is completely dissociated in water. It can therefore be used to prepare salts containing the Cl anion called "chlorides". As a strong acid, hydrogen chloride has a large "K". Theoretical attempts to assign the p"K" of hydrogen chloride have been made, with the most recent estimate being −5.9. However, it is important to distinguish between hydrogen chloride gas and hydrochloric acid. Due to the leveling effect, except when
