HCL+ NaOH---> NaCL+ H2O

2) A process used to derive the concentration of a substance by using the formula for neutralization, using an indicator to check the pH level of the product at any given point.
Utilizes the formula : C1V1 = C2V2

3) Equivalence point is the point where there are equal amounts of atoms of an acid and base, whereas end point is where the indicator shows that the pH of the product is neutral, and is an estimation of the Equivalence Point

1)  Neutralisation is a reaction that takes place between an acid and a base. (A reaction where acidity or alkalinity is removed).

In chemistry, neutralization or neutralisation (see spelling differences), is a chemical reaction in which an acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the acid strength of the reactants. Neutralization is used in many applications.
2. Titration, also known as titrimetry,^[1] is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator^[2] is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand^[3] to determine concentration. The volume of titrant reacted is called titration volume.]]> 2018-02-06 07:19:51 UTC https://padlet.com/georgea6/bgr4sx86ej5m/wish/228455398 https://padlet.com/georgea6/bgr4sx86ej5m/wish/228455505 1. Neutralization is the chemical process between an acid and a base to give salt and water.

3.  Titration is the process of determining the concentration of an unknown substance through the concentration of a known substance.

4.  Equivalence point is the point at which the both substances are chemically equal. Endpoint is the point where the colour of the indicator changes. ]]> 2018-02-06 07:20:31 UTC https://padlet.com/georgea6/bgr4sx86ej5m/wish/228455505
