What Effect The Concentration Of Acid Has On The Rate Of Reaction
The Effect of concentration on the rate of reaction Aim The aim of this experiment is to find out what effect concentration has on a rate of reaction. Prediction I predict that the higher the concentration of the acid, the faster the reaction will take place, this is because when there is a higher concentration, to a certain extent, there is more particles, so the higher the concentration of acid, the more particles there would

Acid Rain
Acid rain is a kind of air pollution. When coal, oil, or gasoline are burned, they release harmful gases into the air. These gases mix with the moisture that is always present in the air and form weak acids. Wind can carry the acidic droplets huge distances. Eventually, these droplets return to the ground as acid rain or as acid hail, snow, sleet, or even fog. Acid rain looks, feels, and tastes just like clean

Acid Rain
Acid rain is considered by many people to be one of the most serious environmental problems of our time. It is a global problem that is slowly eating away at our world. Angus Smith came up with the word acid rain when he wrote about pollution in England. Most rain is naturally acidic because of the carbon dioxide (CO2) in the air that dissolves with rainwater and forms a weak acid. This kind of acid

Rate Of Reaction
Rate of Reaction Aim: To find out how different concentrations change the rate of reaction Theory: In this experiment the collision theory is in use. It means that when the concentrates solutions of hydrochloric acid is use, more particles are found in the same space, which means they are more likely to collide with each other. the more the concentrated the solution, the more of the collisions with the particles, which increases the rate
