Indicator

Nursing-Sensitive Indicators a) Discuss how an understanding of nursing-sensitive indicators could assist the nurses in this case in identifying issues that may interfere with patient care. Nursing-sensitive indicators are critical determinants that the nursing profession utilizes to describe the efficiency that nursing interventions bring as well as positive patient outcomes. The case of Mr. J is truly saddening as the evidence describing the entire case indicates that the nurses that attended…

Antacids are a class of medicine which assist to balance the acidity/ pH balance in your stomach. The pH system is a scale which measures how acidic a substance is or how basic a substance is or if a substance is neutralized. Antacids have the ability to give relief for heartburn, indigestion or symptoms of acid reflux. There are many types of antacids such as calcium, aluminum and magnesium. They’re many ways to consume antacids such as liquids, tablets and chewable tablets. The experiment will…

figure out the pH of each substance we use pH paper and pH machine. Then we record the results of each substance. The reason that the results came out the way it did because procedures were follow right. When testing the substances the pH paper has indicators that help determine the color of the paper and in return the pH of the substance. The…

can be determined by the white vinegar with the known concentration of sodium hydroxide from the previous lab. (Eq 2). CH3CO2H(aq) + NaOH(aq) = CH3CO2Na(aq) + H2O(l) (Eq 2) The purpose of indicator used to determine the end point of the reaction when both the reactants and product are colorless. The experiment goal of the lab is to determine the concentration of acetic acid (CH3CO2H) in the commercial white vinegar brand. Procedure and…

The list of errors start from the beginning of the experiment. Although the numbers seem to be close to the actual values, there is still room for error with the numbers. What the class noticed first is that we could have been working with very impure benzoic acid. The benzoic acid we were given was made by the 102 chemistry students, meaning that it wasn’t properly made. Students have said that they were rushed and weren’t able to take their time to filter the solid out of the solution. We had…

The four methods used for quantification of alkalinity (4) are summarized below: •Use of a pH indicator: a change in the color from pure yellow to orange is observed and recorded when a known pH is reached. In this his experiment we used methyl orange as indicator The consumed volume until specific pH allow us to know how much volume is required to reach the endpoint. •Visual identification from titration curve; the data are recorded…

litmus paper will demonstrate that a solution contains an acid. However, if the solution contains a base the paper will turn blue, and if it turns red the solution is an acid. Also, like the litmus paper, Multip-pH is a paper impregnated with an indicator solution. The paper is dipped in the solution and is matched with a pH color chart. Furthermore, if both pink and blue litmus paper fail to change color, than the solution is neutral. An example of a neutral solution would be distilled water,…

I. DETERMINATION OF ACIDITY: Acidity was obtained by titrimetric method. Required chemicals are: - Methyl orange indicator (1-2 drops), Phenopthelene indicator (1-2 drops), and titrate with NaOH (0.02 N) till orange colour change to pink color. J.DTERMINATION OF DO: WINKLER METHOD DO was obtained by titrimetric method. The amount of Dissolved Oxygen, or DO, in water is expressed as…

number of mL or moles needed to reach the endpoint, the greater the buffering capacity. This is because it signifies that the highest concentration buffer resist the most change in pH. If a student were to use the bromothymol blue indicator instead of the thymol blue indicator in Part B, he/she would not be able to test the buffering capacity of acetic acid/sodium acetate buffer by adding HCl because bromothymol blue changes color when the buffering…

household items that could be analyzed by titrations are fruit juice, Cola beverages and household ammonia. 3. Why is it necessary to add an indicator? Describe how an indicator works. The reason why it is necessary to add an indicator is to determine the concentration of an unknown solution. By reacting with H+ and OH-, these are weak acids and bases. If an indicator is a…
