  • Case Study Notes: Acid Base Balance Study Guide

    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…

  • Differences Between Acids And Bases

    Introduction: Acids and bases are often described using the Bronsted-Lowry theory which states that acids are proton donors, while bases are proton acceptors (Thorne, 78). This means that an acid has additional H+ ion(s) that can be given, whereas a base lacks these ions and will accept them. Acids and bases can further classified as strong or weak. A weak acid, such as HF, will not ionize completely, meaning that only some of the H+ ions will be lost. A strong acid will however, will release…

  • Acids And Bases Essay

    Part A: Background Information Acids and bases are very common in today’s society, and they can be found in most households. Acids can be found as by-products of air pollution, concrete cleaner, food flavouring and is produced by the muscle. Bases are found in most cleaning products as ammonia or sodium hydroxide, and they also treat indigestion. There are many ways that acids and bases can be defined by their chemical properties. The Bronsted-Lowry definition states that acids are proton…

  • Titration Lab

    concentration is determined with a solution of a known concentration. In this case, the known solution, NaOH, is dripped into the unknown, unknown #2, with a burette. The NaOH is dripped until the reaction is complete, while measuring the pH per amount of base added. Using the data collected, the equivalence point can be found and the concentration can be calculated. Then the KA can be found at specific points (20%, 40%, etc). After finding the KA’s at specific points the average can be taken…

    they can be strong or weak. Strong acids completely dissociate their H+ and weak acids only partially dissociate their H+.3 This means that a strong acid cannot return to its initial state once it undergoes a reaction. On the other hand, a weak acid can return to its initial state. Bases are cations that have a hydroxide anion added into their molecular formulas. Bronsted defined bases as a proton acceptor.3 Just like acids, bases can be either strong or weak. Strong bases completely dissociate…

  • Buffer Solution Research Paper

    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…

    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 were used to help apply basic theories about acids and bases such as pH.…

  • Chemical Equilibria Lab Report

    Analysis of Chemical Equilibria INTRODUCTION The reaction being done with borax and HCl is an acid base reaction. The K constant expression of the reaction is Kc = [Na^+][B4O7^-2]. A titration is needed for this experiment because when a strong acid with a known concentration is added to a weak base, the unknown concentration of the weak base can be found, which can then find the moles of the weak base, which can then find the Kc. The first law of thermodynamics is that energy can’t be created…

    Lab 14/ Test 6: Determination of Acid Dissociation Constants through Titration Sabrina Tom I.Abstract The two unknown solutions A and E were titrated with NaOH solutions. For each solution, one fast and three slow titrations were done to see where the pH rose exponentially. The unknown solutions A and E were determined to be Pyridinium ion acid and oxalic acid, respectively. II.Theories One significant concept throughout this lab is titrations. A titration is a lab method analyzes a…

  • Henderson Hasselbalch Equation For Buffers

    Since acetic acid is considered a weak acid (strong within the scale of weak acids), there is a range at which the acetic acid and acetate will form a stable buffer. Using the Henderson-Hasselbalch equation for buffers, it’s possible to calculate the pH based on the ratio of acid to conjugate base, or calculate the ratio given the pH and pKa value. Finding charge on a protonated amine: The pKa value given for the amino group on any amino acid specifically refers to the equilibrium between the…
