Investigating The Factors Which Affect The Rate of Reaction Between Limestone and Acid Rain(Hydrochloric Acid)

Background knowledge Rainwater is always slightly acetousic, as carbon dioxide in the address line dissolves in rain dget to form carbonaceous pointulent. Acid rain is rain, coke or fog that is bemire by acid in the atmosphere and damages the surroundings. 2 common zephyr pollutants ferment rain: sulphur dioxide (SO2) and newton oxide (NOX). When these substances atomic number 18 released into the atmosphere, they faeces be carried over long distances by prevailing winds originally locomote to earth as vitriolic rain, snow, fog or dust. When the environment cannot neutralize the acid creation deposited, damage occurs.          When an acid is neutralize by a carbonate A SALT, WATER, and blow DIOXIDE. Acid          + hundredate         à          flavor +                   peeing +         Carbon Dioxide Hydrochloric Acid + atomic number 20 Carbonate à Calcium Chloride +Carbon Dioxide +Water 2HCl          +         CaCO3 à CaCl2 +          CO2 + H2O Secondary Source Internet Factors To Vary And Control The variables I volition be considering are: ·          pull at which the sample ensues. ·         Surface sphere of lure of the limestone chip(s). ·         Temperature at which the reaction takes place. ·          great deal of acid. ·         Molarities of acid.

The reason that these are the variables is that if independently one was changed even if in a little way, they kick in the rate of reaction both making it faster or slower. Though in my experiment I am strenuous to find out how ever-changing the molarities of the acid mends the rate of reaction. So in this way I must(prenominal) only bring the molarities of the acid as a variable, and everything else in the experiment must tarry fixed for the experiment to be fair. All of the variables above affect the rates of reactions in their own ways: ·         Pressure at which the experiment takes place will affect the experiment as the reaction...
