The reaction between an acid and a base is known as a neutralisation reaction. Often when an acid and base react a salt and water will be formed. We will look at a few examples of acid-base reactions. In chemistry the word salt does not mean the white substance that you sprinkle on your food this white substance is a salt, but not the only salt. A salt to chemists is a product of an acid-base reaction and is made up of the cation from the base and the anion from the acid. Hydrochloric acid reacts with sodium hydroxide to form sodium chloride a salt and water. Hydrogen bromide reacts with potassium hydroxide to form potassium bromide a salt and water.
Titration Part 1: Scientific Introduction The technique known as titration is an analytical method commonly used in chemistry laboratories for determining the quantity or concentration of a substance in a solution. In a titration, an analyte -- the substance whose quantity or concentration is to be determined -- is reacted with a carefully controlled volume of solution of accurately-known concentration called a standard solution. The standard solution also known as the titrant is usually added to the solution containing the analyte by means of a buret , a piece of volumetric glassware capable of accurately measuring solution volumes. There are many types of titrations in common use in the analytical chemistry laboratory. Each type uses a different kind of chemical reaction.
A neutralization equation is a chemical reaction that involves the combination of a strong acid and a strong base. The products of such a reaction are typically water and a salt. It is useful to know how to solve neutralization equations because they are often involved in chemistry experiments and they can help you to better understand the differences between acids and bases. Tables of strong acids and bases are often provided for reference. Write down the chemical formulas for the strong acid and the strong base that are the reactants of the neutralization equation. The problem will usually tell you what the reactants are.
The changes in temperature caused by a reaction, combined with the values of the specific heat and the mass of the reacting system, makes it possible to determine the heat of reaction. Heat energy can be measured by observing how the temperature of a known mass of water or other substance changes when heat is added or removed. This is basically how most heats of reaction are determined. The reaction is carried out in some insulated container, where the heat absorbed or evolved by the reaction causes the temperature of the contents to change. This temperature change is measured and the amount of heat that caused the change is calculated by multiplying the temperature change by the heat capacity of the system. The apparatus used to measure the temperature change for a reacting system is called a calorimeter that is, a calorie meter.
Compare the temperature change when 50 mL of 1. The amounts of reactants that react influences q, the heat exchanged during an acid-base neutralization reaction. This demonstration is usually performed when topics in thermochemistry are being discussed. The big idea for most calorimetry demonstrations is energy is conserved. Energy cannot be created or destroyed, but it can be exchanged.

A chemical reaction by definition forms new chemicals called the products from the initial chemicals called the reactants. It should make sense that the identity of the products formed depends on what reactants we start with. Adding an acid to a base is an example of a chemical reaction, so we should expect to see new products. Although there is a pattern to this type of reaction, ultimately the products formed depend on what acid and what base are used. At first glance, this question has a simple answer. Most introductory chemistry books will teach that the reaction between an acid and a base is called neutralization, and the products formed are water and a salt.
Equal volumes, The resultant solution records a temperature of The heat gained by the resultant solution can be calculated using. Since the solutions are mostly water, the solutions are assumed to have a density of 1. This reaction is classified as an exothermic reaction.

Titration of a strong acid with a strong base is the simplest of the four types of titrations as it involves a strong acid and strong base that completely dissociate in water, thereby resulting in a strong acid-strong base neutralization reaction. This titration requires the use of a buret to dispense a strong base into a container of strong acid, or vice-versa, in order to determine the equivalence point. The purpose of a strong acid-strong base titration is to determine the concentration of the acidic solution by titrating it with a basic solution of known concentration, or vice-versa, until neutralization occurs. As both the acid and base are strong high values of K a and K b , they will both fully dissociate, which means all the molecules of acid or base will completely separate into ions. The pH at the equivalence point for this titration will always be 7. In addition, the anion negative ion created from the dissociation of the acid combines with the cation positive ion created from the dissociation of the base to create a salt. Therefore, the reaction between a strong acid and strong base will result in water and a salt.
