A buffer solution can maintains a narrow range of pH even when strong acid are added. In our experiment‚ we can see water is not a buffer‚ water can undergo very big changes when small amounts of strong acid or strong bases are added. When the strong acid‚ 100µl HCl was added into the dd water‚ the pH value changed from 7.38 to 5.83 which mean the dd water has turn into acid. The same phenomenon occurs while strong base‚ 100µl NaOH was added into the dd water. The pH value changed from 7.07 to 9

are different types of toys for different age groups. All toys are tested for safety before being putting on a shelf in a store.

For example‚ Toys R Us have different section for kids under 2 in the back‚ beside that section is the baby section‚ and so on… The question is that will it stimulate or encourage a child to play with that toy or move on to different toy?! When it comes to toys there are different categories

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

Chapter 7 Activity-Based Costing: A Tool to Aid Decision Making Solutions to Questions 7-1 Activity-based costing differs from traditional costing systems in a number of ways. In activity-based costing‚ nonmanufacturing as well as manufacturing costs may be assigned to products. And‚ some manufacturing costs—including the costs of idle capacity--may be excluded from product costs. An activity-based costing system typically includes a number of activity cost pools‚ each of which has its

problems such as diabetes‚ heart disease‚ arthritis‚ and hypertension. What is the solution to this problem besides medication and surgery? One of the easier and simpler solutions is to drink alkaline water. To understand what alkaline water is‚ we must know where it comes from‚ and how it works. Knowledge of the benefits of alkaline water for treating obesity will help solve this national problem. SOLUTION FOR OBESITY This research report discusses the benefits of alkaline water for obesity

Chemistry 112: Anion Analysis Page 7 ANION ANALYSIS M uch of the work you will be doing in the Chemistry 112 laboratory will be concerned with identifying positive and negative ions‚ that is‚ cations and anions‚ in solutions whose composition is unknown. This procedure is called QUALITATIVE ANALYSIS. The modern chemist frequently wishes to identify the constituents in a very small amount of substance‚ and so he depends heavily on instrumental methods of analysis. While the procedures

Electrolytic Solutions Solutions are sometimes grouped according to their ability to conduct electricity. Substances whose solutions conduct electricity are called electrolytes and those that do not conduct electricity are called nonelectrolytes. Also electrolytes can be strong or weak. Under strong electrolytes we have NaCl and CaCl2 which are ionic compounds‚ HCI‚ HNO3‚ HBr and H2SO4 are under acids and NaOH‚ KOH‚ and LiOH are under bases. Weak electrolytes are ionic compounds and slightly
