The copper metal strip was placed in the silver nitrate and dilute(3M) sulfuric acid‚ the lead metal strip was placed in the copper(II) nitrate and the zinc metal strip was placed in the lead(II) nitrate‚ magnesium sulfate and dilute(3M) sulfuric acid. Overall‚ putting these different strips of metal into different solutions will help determine the reactivity of copper

We created the gases by bubbling each gas into the water to create the three acidic solutions we were looking for. Once that

PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the

and industrial applications. Citric Acid is one of the organic acids commonly used as a chelating agent. It is considered an excellent chelating agent that binds metals. It is used to remove lime scale from boilers and evaporators. It can be used to soften water‚ which makes it useful in soaps and laundry detergents. By chelating the metals in hard water‚ it lets these cleaners produce foam and work better without need for water softening devices. Citric acid is the active ingredient in some bathroom

There are different definitions proposed by different scientists about what makes an acidic solution. Particularly‚ there were two scientists who independently proposed essentially the same theory about the definition of acids and bases. In 1923‚ Johannes Nicolaus Bronsted and Thomas Martin Lowry‚ from Denmark

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus
