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 credit line dissolves in come d experience down to form carbonic acidulent. vinegarish rain is rain, play false or fog that is polluted by acid in the atmosphere and damages the surroundings. Two common zephyr pollutants acetify rain: sulphur dioxide (SO2) and nitrogen oxide (NOX). When these substances are released into the atmosphere, they faeces be carried over long distances by prevailing winds originally returning to earth as acidic rain, snow, fog or dust. When the environment cannot neutralize the acid being deposited, damage occurs.          When an acid is liquidate by a carbonate A SALT, WATER, and CARBON DIOXIDE. Acid          + Carbonate         à          flavor +                  Water +         Carbon Dioxide Hydrochloric Acid + atomic number 20 Carbonate à Calcium Chloride +Carbon Dioxide +Water 2HCl          +         CaCO3 à CaCl2 +          CO2 + piddle Secondary Source Internet Factors To Vary And Control The variables I leave alone be considering are: ·          pull at which the investigate ensues. ·         Surface sphere of influence of the limestone chip(s). ·         Temperature at which the reaction takes place. ·          strength of acid. ·         Molarities of acid.

The reason that these are the variable s is that if severally one was changed even! if in a little way, they reach the rate of reaction either making it faster or slower. Though in my experiment I am toilsome to find out how ever-changing the molarities of the acid affects 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 remain 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...
