As part of chemistry class, you may have to identify unlabeled solutions. If you have a solution you suspect may be hydrochloric acid but don't know for sure, the quickest way to test uses silver nitrate solution. The test is also a good introduction to precipitation, where an insoluble so...
Place the test tube into the beaker of boiling water. Allow the test tube to boil for five minutes. Add a small amount of starch solution and Benedict's reagant to a second test tube. Then rinse the pipette and add a small amount of hydrochloric acid to the second test tube. Place th...

A cursory examination would immediately reveal that a solution of acetic acid is colorless and has that unmistakable and pungent distilled-vinegar scent and sour taste. Producing it is a two-step process. First, a carbohydrate-rich organic material, like grapes, is fermented to make an alcoholic...
Every NASA launch leaves a huge cloud of exhaust and chemicals in its wake. Alternative, more eco-friendly rocket fuels have made a number of advances in recent months. Here are some of the latest options to fuel a cleaner, more efficient rocket launch.
Convert the magnesium hydroxide obtained in Step 1 to magnesium chloride hydrates with hydrochloric acid (HCl). The following equation shows this reaction: Mg(OH)2 + 2 HCl ? MgCl2 + 2 H2O. This reaction is known as the \"Dow Process\" and is used on a commercial scale. ...
What is the salt that is produced when ammonia (NH3) and hydrochloric acid (HCl) react together? Nitrogen and hydrogen gas react to form ammonia. If a sample of 3.50 moles of H was reacted with excess nitrogen, how many moles of NH would be produced?
even in very dilute concentrations. Compare that to acetic acid (the acid in vinegar), of which only about 1% dissociates in water—and yet that's still enough to make our mouths pucker. (Soy sauce, for reference's sake, is about 10 times weaker as an acid than vinegar, based on the...
