Maximilian Ziegler Candidate number 000-495-022 3IB Investigating the effect of acid rain on building materials Planning (a) Problem The aim of this experiment is to examine the effect of different variables - pH-value, material and its mass - on how acid rain effects buildings and sculptures made of marble and limestone. Hypothesis The lower the pH of sulphuric acid used, the more of the building material will be dissolved. When the same pH of sulphuric acid is used for the same material, the initial mass will play a role. The more it weighs in the beginning, the more weight it will lose. I also assume that the pH-value will increase as marble/concrete should react like base with the sulphuric acid. Possible Variables - pH-value - Materials - Size/mass of the material used Planning (b) Apparatus/ Materials - 4 little pieces of marble (CaCO3) - 1 little piece of concrete - Sulphuric acid (H2SO4) - Several test tubes with corks - Ph-meter - Beakers - Oven - Balance - tweezers Procedure First of all,...
