Equilibrium constant

The Ka is an acid dissociation constant, it is a quantitative measure of the strength of an acid in solution. The pKa is defined as the negative log of the Ka, pKa= -log Ka. The lower the value for the pKa the more acidic the acid (greater concentration of H+ ions). The pKa of a compound relates to how likely, at a given pH, the compound will be ionized. The Henderson-Hasselbalch equation is used to quickly…

dioxide is heated and subjected to high pressure to produce sulfur trioxide, 2SO2(g) + O2(g) → SO3(g). This is due to the fact that sulfur trioxide’s equilibrium yield increases when temperatures are low, however, the rate of reaction increases when the temperatures are high. This is because of Le Chatelier’s Principle, which states “if an equilibrium system is subjected to a change, the system will adjust itself to partially oppose the effect of change”. This problem is resolved with the use of…

Xanthan and Chitosan concentration. The Chitosan solution pH was kept constant at 5. The above table gives the inference that when Xanthan concentration is less than or equal to 0.5% or Chitosan concentration is less than or equal to 0.5%, the capsules formed are unstable. Similarly, amorphous capsules were reported when the concentration of Xanthan was varied as shown in the given table. The Chitosan solution pH was kept constant. This phenomenon was due to the increase in viscosity of…

What are buffer solutions? Buffer solutions are solutions in water that mark the mixture of acids and bases. They assist in neutralization response to a certain quantity. Acidic buffer answers are those that have robust acids and weak bases as their components. they're used for neutralizing alkaline solutions. Alkaline or primary buffer answers are those who have sturdy alkalis and weak acids within themixture. they're used for neutralizing acidic aqueous answers. Buffer solutions in the blood…

Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items…

What results would lead you to the conclusion that the material tested has high potential for AMD generation and would indicate that more extensive and intensive tests should be done to confirm the results. When looking at the Paste pH and Electrical Conductivity Tests, we are looking for an acidic environment and an environment with a high concentration of salt. Specifically, if our site sample has a pH of less than 4, then that indicates that the sample is acidic. If our site sample has an…

INTRODUCTION 1.1What is an acid-base titration? An acid –base titration is the determination of the concentration of an acid or base by neutralizing the acid or base with an acid or base of known concentration. An acid-base titration is the analysis of the concentration of acids and bases; through this process an acid or base of known concentration neutralizes an acid or base of unknown concentration. The neutralization of an acid or base in acid-base titration can be measured with either a…

The % relative standard deviation (% RSD) was found to be below 5 % for all the four analytes in system precision and below 6 % in method precision. The data as shown in Table 3.4.3.3.3 and 3.4.3.3.4. LOD values observed for Hydrazine carbamate and Hydrazone carbamate were 0.0018 µg per mL and 0.00092 µg per mL respectively. The LOD value observed for both 1-Hydroxy benzotriazole and 2R, 3S Chlorohydrine hydrochloride were 0.0019 µg per mL. The LOQ values observed for all four analytes were…

Acid Base Balance Study Guide Definition: The body’s ability to regulate and compensate for variances of the acidity or alkalinity of body fluids through mechanisms in the brain, kidneys, lungs, and buffering system. Concept Key Terms: • Acid: any substance that has a pH less than 7.0 • Acidosis: the condition of having too much acid build up in body fluids, below 7.35 • Alkalosis: the condition of having too much alkaline build up in body fluids, above 7.45 • Anion: a negatively charge…

Symmetry Writing Exercise Paragraph 1 The research paper written by J. Haines, O. Cambon and S. Hull aims to understand how Iron III phosphate (FEPO4) behaves under high temperatures and at which temperature would we start to observe structural transition of Iron III phosphate. As found by the researchers, the temperature where one is able to witness a structural change of Iron III phosphate, a transition from α-β would be at the temperature of 980K. As the researchers have highlighted, there…
