Thus, the concentration of OH- in the solution does not equal the initial concentration of the base, and the vast majority of the base molecules remain un-ionized. A solution of a weak base involves equilibrium between an un-ionized base and its conjugate acid. The equilibrium constant for this reaction is Kb, often reported as pKb. The pH of a weak base solution can be determined from the initial base concentration and the pKb.

If the strong base is in excess, then the pH can be determined from the moles of excess hydroxide ion and the total volume of the solution. If the strong acid is in excess, then the pH can be determined from the moles of excess hydronium ion and the total volume of solution. A titration curve, plotting pH against the volume of titrant added, is useful for summarizing results from a titration. At the equivalence point, the number of moles of titrant added is equal to the number of moles of analyte originally present. This relationship can be used to obtain the concentration of the analyte. The protons on a molecule that will participate in acid-base reactions, and the relative strength of these protons, can be inferred from the molecular structure.

Strong acids have very weak conjugate bases that are stabilized by electronegativity, inductive effects, resonance, or some combination thereof. Carboxylic acids are one common class of weak acid. Strong bases have very weak conjugate acids. Common weak bases include nitrogenous bases such as ammonia as well as carboxylic ions. Electronegative elements tend to stabilize the conjugate base relative to the conjugate acid, and so increase acid strength. The protonation state of an acid or base the relative concentrations of HA and A- can be predicted by comparing the pH of a solution to the pKa of the acid in that solution. Acid-base indicators are substances that exhibit different properties such as color in their protonated versus deprotonated state, making that property response to the pH of a solution.

A buffer solution contains a large concentration of both members in a conjugate acid-base pair. The conjugate acid reacts with added base and the conjugate base reacts with added acid. These reactions are responsible for the ability of a buffer to stabilize pH. The pH of the buffer is related to the pKa of the acid and the concentration ratio of the conjugate acid-base pair. This relation is a consequence of the equilibrium expression associated with the dissociation of a weak acid, and is described by the Henderson-Hasselbalch equation.

The change in pH on addition of acid or base to a buffered solution is therefore much less than it would have been in the absence of the buffer. When a buffer has more conjugate acid than base, it has a greater buffer capacity for addition of added base than acid. When a buffer has more conjugate base than acid, it has a greater buffer capacity for the addition of added acid than base. Quick Links.

The Stoichiometry Set-up Method lesson plan shows students how to follow a process of visual cues in combination with a step-by-step problem solving method for different types of stoichiometric problems. This method can be particularly beneficial for students who struggle with completing multi-step calculations. Read more about this lesson in the September issue of Chemistry Solutions. For more advanced students, use the How to do Stoichiometry Problems lesson, which includes a series of templates for performing stoichiometry problems.

The lesson also includes a practice worksheet for students to use to practice using the templates. Use the simulation Chemical Reactions and Stoichiometry to give your students extra practice on the topics of reaction types, balancing equations, and stoichiometry calculations. The simulation is set up as a short quiz that includes five types of chemical reaction that students have to identify and balance. They are then asked to complete one of the following types of stoichiometry problems: mole-mole, mass-mole, mole-mass, mass-mass, mole-molecule, atoms-mass, or molecule-mass. Follow up your lesson with the Baking Soda Stoichiometry lab which allows students to decompose baking soda and use stoichiometry to determine the proper balanced chemical equation of its decomposition. Then use the Chemical Reactions and Stoichiometry simulation to give your students some more practice using a quiz that challenges their knowledge of reaction types, balancing equations and solving stoichiometry problems.

During this quiz based activity, students are presented with five different reactions to analyze, each having three related questions to answer. The questions are randomized so students will not have the same order as their peers. Additionally, there are 20 possible chemical equations in the quiz, so students can complete it several times without receiving the same problems. Finally, connect stoichiometry to real life with the Stoichiometry of Air Bags lesson plan which connects the concept of gram to gram stoichiometry calculations through a scenario related to air bags. Students are tasked with calculating the amount of sodium gas NaN3 that must be produced to inflate a vehicle air bag to the correct size. Follow-up practice problems are also provided. Limiting Reactant Introduce the topic with the Limiting Reactant Animation which allows students to visualize at the particulate level what happens in a limiting reactant problem.

A number of limiting reactant scenarios are animated, including a simple example of how to build a bike to introduce the concept of limiting reactant. Conservation of mass is also demonstrated by calculating masses from the mole quantities of the reactants and products. You might prefer to use one of our teacher demonstrations to introduce the topic to your students. Students observe a series of reactions between acetic acid and sodium bicarbonate in Zip-lock bags with the Introducing Limiting Reactants demonstration. After observing the reactions, students analyze the quantities of reactants used as well as the results in order to understand the concept of limiting reactants. They will also determine if the reaction is an endothermic or exothermic process based on their observations. The demonstration, Understanding Limiting Reactants is a similar resource, performing a series of reactions between acetic acid and varying amounts of sodium bicarbonate in order to inflate several balloons.
