Neutralisation - How much acid is required to neutralise a base :: GCSE Chemistry Coursework Investigation

Neutralisation - How much hot is required to neutralise a ignorantIntroduction============Neutralisation is the reaction of a base with an astringent to form aneutral solution which contains salt and water.Acid + Base Salt + Water---------------------------In my experiment I am trying to bring forth let extinct how much acid it takes toneutralise a base to form a neutral solution. I will use one molar of nitrous Acid as the acid and one molar of Ammonium Hydroxide as thebase. So this will be a 11 ratio. (Molarity = how umteen molecules ofthe acid or alkali per 1000 cm3 (1 litre) of water.)azotic Acid + Ammonium Hydroxide Ammonium Nitrate + Water-----------------------------------------------------------HNO + NH OH NH NO + H O noggin bonding must take place to form the salt and the water. Ions film been formed because the original atoms stupefy bemused or gainedelectrons. These ions then have galvanizing charges because they do nothave the same amount of positive protons and negative electrons. Atomsthat loose electrons are called cations and have a positive charge.Atoms that have gained an electron and have a negative charge arecalled anions.The General equation for making water isH + OH H O---------------In this equation the Hydrogen ion has bemused and electron and has becomea cation with a positive charge. The Hydroxide ion has gained anelectron and has become a negatively charged anion. loft bonds arecreated when ions combine in order to share and thus becomeelectricly stable.From the main neutralisation equation I have circled the parts to makewaterHNO + NH OH NH NO + H OEquipmentAmmonium Hydroxide (base)Nitric Acid (acid)Methyl Oxide - (to show the pH of the solution)Clamp (to hold the burette safely and securely in place)burette - (to hold the acid)White Tile Funnel (to pour the acid into the burette)Goggles - (to protect the eyes)Conical Flask (to hold the base)Measuring Cylinder (to measure out the acid and the base)PreliminaryBef ore we began our practical our teacher performed the experiment asan example to our class. The teacher set up the equipment as shownabove. She informed us of the synthetic rubber precautions and then began theexperiment. She used 20ml of Ammonium Hydroxide (base), placing thatin the conical flask. Then she added 6 drops of Methyl Orange(indicator). From the burette she added 12ml of Nitric acid andswilled the conical flask. afterwards this point she decided to control theamount added to the base and indicator by using the burette.Neutralisation - How much acid is required to neutralise a base GCSE Chemistry Coursework InvestigationNeutralisation - How much acid is required to neutralise a baseIntroduction============Neutralisation is the reaction of a base with an acid to form aneutral solution which contains salt and water.Acid + Base Salt + Water---------------------------In my experiment I am trying to respect out how much acid it takes toneutralise a base to form a neutra l solution.
