believe that if the amount of sodium citrate is too low or too high‚ the sodium alginate solution would not form into a ball. The recommended amount of sodium citrate to be added to the sodium alginate solution was ⅛ teaspoon‚ or 0.5 grams. We supposed that if we exceeded this measurement‚ the sodium citrate would unbalance the whole solution‚ making the balls deform. If we added too little of the sodium citrate‚ we thought that there would be too little for the sodium citrate to fully do its job of

BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the following

One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into account

Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution

Flowers and Acid Call them freaks‚ the underground‚ the counterculture‚ flower children‚ or just simply hippies‚ they are all loose labels for the youth culture of the 60’s that transformed life in the West as we knew it‚ introducing the spirit of freedom‚ of hope‚ of happiness‚ of change‚ and of revolution (Miles 9). The years that made up the 1960’s were some of the most exciting and turbulent years in American history. The post World War II baby boomers grew up. A president and

Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday‚ February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen cations present in the acid. B. The sodium sulfate is boiled because experiments have shown that barium sulfate is 50 times more soluble at 100°C than at room temperature. At

Title: Preparation and Standardization of a Sodium Hydroxide Solution Objective/Purpose: The objective of this experiment will be the standardization of sodium hydroxide using potassium hydrogen phthalate by the titration method. Introduction: The concentration of solutions can be reported in terms of molarity and normality. Molarity is equal to: HCL‚ HBR‚ H2SO4‚ HNO3 M = mol Solute (mol) (Monoprotic) (Diprotic) _______________ V(L)g solutions (L)

Sodium hypochlorite‚ also known as chlorine bleach‚ soda bleach‚ or household bleach is a chemical with the formula NaClO. A common way sodium hypochlorite gets into the San Francisco bay is through daily household cleaning products such as laundry bleach. In a survey conducted by The Clorox Company‚ it was found that four out of five households use sodium hypochlorite bleach for their laundry. Since laundry detergent companies are not required to list every ingredient‚ customers are often not aware
