formed when a neutral metal atom: Fe acting as a Lewis acid‚ reacts with some neutral molecules‚ acting as Lewis bases; or when a metallic cation‚ acting as a Lewis acid‚ reacts with any of a variety of organic or inorganic molecules‚ cations‚ or anions‚ acting as Lewis bases. These Lewis bases: C2O4 and H2O are called ligands. (Lewis acids are electron pair acceptors and Lewis bases are electron pair donors. Ferrous ammonium solution is added with oxalic acid

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.

KERRY ACIDS‚ BASES‚ & NEUTRALS September 20‚ 2010 EXPERIMENT Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pHs balanced and neutral? Information pH measures how acidic or alkaline a solution is. Its concept was introduced in 1909 by biochemist Soren Sorensen. The scale ranges from 0-14. Solutions that range from 0 to 6 are considered to be Acidic. Solution that’s on the Acidic end of the scale is low in ph‚ high in hydrogen ion‚ and low in hydroxyl ions. An

“enthusiasm” are the first and the most important steps through the door of success. Having a strong foundation in our life is so important. For Example‚ for building a tower‚ engineers first start building the base. The base is the most important part of the tower; with out a strong base‚ the possibility of the tower falling is high. In our life we will build other things based on these two cornerstones‚ so we must have develop good habits about working hard and being enthusiastic. This will make
