Measuring Acid Reactions

Measuring blistering answers Introduction: This experiment review willing show how distinct each savage chemical reaction is contrary from each other. There were two various experiments; one measures the temperature of the reaction and the other measures the pH take aim. The reaction can be heat-absorbing or energy-releasing. The differences between them are simple; exothermic puts tabu muscle which removes it warm to touch. As for endothermic the reactions pulls in energy and makes it cold to touch. The other experiment measured the pH level in the reaction. The reaction consisted of sodium hydroxide and hydrochloric blistery to a fault to see at which point the reaction becomes neutralized. Neutralization is a reaction between an acid and a base forming a saltiness and water even just you cant see the salt due to the salt dissolving into the resolvent and the pH level of the reaction near level 7 and has a green sometimes yellowness colour when the genera l indicator is added. The neutralization reaction quip shows how small the gap is to make the reaction neutral. It looks like a stretched out S and the neutralization point is near the shopping centre when the kink up starts to rise. [pic] This is the neutralization curve in the tenderness is the neutral point. Aim: experiment 1 the finishing for the scratch line experiment is to show and collect the data of lead different mixtures of acids and bases. We are looking to find wether the reaction is exothermic or endothermic.

Experiment 2: the aim for this experiment is to criminal insert the pH lev el of a sodium hydroxide and hydrochloric ac! id reaction. Then record it into the graph, it should resemble the standard neutralization curve, as shown under the introduction. Materials: what you will need for both experiments: Experiment 1: ? 20g baking soda ? 20g citric acid ? 2 cm strip of magnesium ? 50 ml of 5M HCl acid ? 50 ml measuring cylinder ? Thermometer probe Experiment 2 ? 50 ml 5M NaOH base solution ? Universal indicator...If you emergency to get a full essay, order it on our website: BestEssayCheap.com
