HC2O4−. A salt with this anion is sometimes called an acid oxalate‚ monobasic oxalate‚ or hydrogen oxalate. The equilibrium constant (Ka) for loss of the first proton is 5.37×10−2 (pKa = 1.27). The loss of the second proton‚ which yields the oxalate ion has an equilibrium constant of 5.25×10−5 (pKa = 4.28). These values imply that‚ in solutions with neutral pH‚ there is no oxalic acid‚ and only trace amounts of hydrogen oxalate.[1] The literature is often unclear on the distinction between H2C2O4‚

Binge drinking is a modern epithet for drinking alcoholic beverages with an intention of becoming intoxicated by heavy consumption of alcohol over a short period of time. Binge drinking is out of control in many college town campuses. The actual act of drinking alcohol is not necessarily the big issue here; it is the way people are drinking it whether they are legally old enough or not. The issue is binge drinking of college students mostly or anyone really. Drinking alcohol can have many consequences

other human that is twenty-one or older. The drinking age was not always what it is today; it has been changed a tremendous amount of times throughout the decades from 1919-present day. There wasn’t a national drinking age before the prohibition that from 1920 to 1930 and after the prohibition‚ most states required age was 18. In 1984 The National Minimum Drinking Age Act was enacted by Ronald Reagan‚ it was a law that required states to raise the drinking age or ten percent of the federal highway funding
