level questions: Neutralisation Reactions

QuestionAnswer
what is titration?an analytical technique used to determine the accurate volumes involved in a neutralisation reaction
What is a neutralisation reaction?the reaction of an acid with a base producing water as one of the products
how is a salt formed in a neutralisation reaction?the hydrogen ion of the acids is replaced by the positive ion of the base to form a salt
how is water formed in a neutralisation reaction?the hydrogen ions of the acid react with hydroxide ions to form water
what type of salts form from hydrochloric acid?chloride salts
what type of salts form from nitric acid?nitrate salts
what type of salts form from sulfuric acid?sulfate salts
what are the products when a metal oxide and an acid react?a salt + water
what are the products formed when a metal hydroxide and an acid react?a salt + water
what are the products when a metal carbonate and an acid react?a salt + water + carbon dioxide
what is a spectator ion?an ion that remains unchanged in a chemical reaction
what are the spectator ions in this balanced formula equation?SO4^2- Ca^2+
what are the spectator ions in this balanced formula equation?Na+ NO3^-
what does removing spectator ions from a balanced formula equation leave behind?the equation representing the overall reaction taking place
what is titration?an analytical technique used to determine the accurate volumes involved in a neutralisation reaction
what is this piece of apparatus and what is it used for?a burette is used to measure the exact volume of acid required to neutralise the alkali. The titre.
what is this piece of apparatus and what is it used for?a pipette is used to measure the exact volume of alkali
what is a standard solution?a solution of accurately known concentration
what is the minimum amount of times you should carry out a titration?3
what is meant by concordant titre values?titre values within 0.2cm^3 of each other
what must be carried out before your first proper titration?a trial/rough titration
when carrying out titration calculations, what must be done to the concordant titre values?must calculate a mean average of them
when is the end point of a titration reached?when there is a permanent colour change of indicator seen in the conical flask
why isn't universal indicator typically used for titrations?large range of colours make it hard to spot the end point of the titration
