concentration. HC2H3O2 (aq) + NaOH (aq) H2O (l) + NaC2H3O2 (aq) The above equation is used to neutralize the acetic acid. The acid reacts with a base to produce water and a salt. Because there’s a 1:1 ratio‚ the moles of the acid must equal the moles of the base in order to reach the equivalence point. As far as the indicators go‚ an acid-base indicator will be used to show when we are close to the end point. For example‚ when HIn is dissociated In - is produced and it is pink. (See equation

Title Laboratory Techniques and Measurements Purpose The purpose of this experiment is to determine mass‚ length‚ temperature‚ volume‚ and density of objects and liquids using common measuring devices and algebraic formulas. The metric system‚ the most common set of measurements used in science‚ which includes meters‚ liters‚ Celsius‚ and grams will be used. Procedure The following items were used within the experiment: (1) Metric ruler with centimeter (cm) and millimeter (mm)‚ (1)

results in a yellowish tint. This means the byproduct of the two is a base. C NH 3 and BTB When two drops of Ammonia and one drop of Bromothymal blue are combined the result remains blue. This means they are base. D HCI and blue dye When Hydrochloric acid and blue dye are combined the result is a base. E Blue dye and NaOCI When Blue dye and Sodium Hypochlorite react are combined the result is green. This means it is a base. F NaOCI and KI When Sodium Hypochlorite and Potassium Iodide

experiment 7) Repeat the entire process using a new 100 drops of milk and ammonia this time Liquid Wide Range pH Narrow Range pH Water Lemon Juice Milk Ammonia Analysis: In this lab‚ one observed that acids and bases affect the pH of milk differently from one another. For example‚ the lemon juice gave the milk a lower pH because of the acidity of the lemon juice. That’s why the milk curdled. Another example‚ when ammonia was added to milk in part II of the lab

and then on a base. The acid we used was hydro chloric acid and the base was ammonia. The acid turned pinkish red when properly titrated and the base turned clear. We used phenolphthalein as the titrate which turns red in acidic solutions and clear in basic solutions. The control aspects of this lab were the hydrochloric acid and ammonia. The independent variable was the titrate the phenolphthalein. We measured how many drops of the phenolphthalein it took to titrate the acid or the base. Research

tell an acid from a base using a simple experiment that can be done in the household. Telling an acid from a base is very important in the world from people that may have a pool in their backyard to those who are chemists and need that information to balance chemical equations. With simple experiments‚ one can tell if the solution they have is a base or an acid. The testable question in this paper will be “can simple tests show that a liquefied solution is an acid or a base?” I will be arguing that

acid and base are mixed together to me an ionic compound or which are 7 on the pH scale or pure water‚ it is also when a base and acid are mixed to make it in a neutral state. What am I wondering? (What are your rough ideas to fix an acidified lake?) I will be finding a base that will work the most effective way‚ also I will find a base that can fix a large amount of acidified lake water with a base that can neutralize it with less then the acidified lake water‚ I will also look for a base that can

For example‚ the reaction of the strong acid HCl with the strong base NaOH produces the salt sodium chloride and water HCl(aq) NaOH(aq) ( NaCl(aq) H2O(l) Since the acid‚ base‚ and salt in this reaction are all strong electrolytes‚ the net ionic equation for this reaction is H(aq) OH-(aq) ( H2O(l) This same result occurs in the reaction of strong acid reacts with a weak base‚ or a weak acid reacts with a strong base.
