What are the hazards?
1.0M Hydrochloric acid is low hazard, 1.0M sodium hydroxide solution is corrosive
What are the risks for the hazards?
Burn skin / eyes when measuring
What is the control measure of the hazards?
Wear gloves / goggles
What is the reaction between hydrochloric acid and sodium hydroxide?
A neutralisation reaction
Give an example of a neutralisation reaction
Reaction between hydrochloric acid and sodium hydroxide
How could we improve the method?
By reducing heat loss
?How would you reduce heat loss?
Putting a lid on
What is the issue if you were to put the chemicals in the fridge then start straight away?
No reactions as particles would not have activation energy -> no energy to collide + react
If you repeat the experiment would you improve accuracy?
No you would need to change to more accurate equipment
What does neutralisation involve?
Acids reacting with bases
What is the equation for the experiment?
NaOH + HCl = NaCl + H2O
How do you calculate energy change?
Energy change = Mass of water X Specific heat capacity of water X Maximum temperature change
