It was originally hypothesised that the reaction time would decrease with higher concentrations of the reactants‚ potassium iodate and sodium bisulfite as collision theory stated that more molecules present in a given volume meant a greater chance they would collide. Furthermore‚ the time was expected to decrease with higher temperatures as it influenced the reactant particles by raising their kinetic energy. However‚ the data collected from this experiment only partially supported this hypothesis

can also be dissolved in a liquid solution. c. Solid Solution- is a mixture of solids spread equally throughout one another. Metal is an example of a solid solution at room temperature. 3. Solubility is the ability of one compound to dissolve in another compound. 4. a. Temperature - Basically‚ solubility increases with temperature. It is the case for most of the solvents. The situation is though different for gases. With increase of the temperature they became less soluble in each other and in

mistake was made. Results Reaction time to a second word or non-word is influenced by the previous word or non-word. The null hypothesis stated that all pairs would have the same mean reaction time‚ regardless of whether the first string was a word or non-word. The alternative hypothesis stated that the mean reaction time for word-non-word pairs would be slower than non-word-word pairs‚ which would be equal to the mean reaction time for non-word-non-word pairs.

Solubility refers to the maximum amount of solute that dissolves in a given amount of solvent at a particular temperature Factors Affecting Solubility 1. Effect of Temperature For some substances to dissolve in a given solvent‚ heat is absorbed. The reaction is endothermic. In this case‚ an increase in temperature increases solubility. For some substances‚ heat is released when they dissolve in a given solvent. The reaction is called exothermic. In this case‚ an increase in temperature

March 18‚ 2012 Title: Types of Chemical Reactions Data: Reaction Observations Evidence #1 It turned a reddish brown and the liquid went clear. The color change proved it was a chemical change. #2 The reaction turned yellow and it separated and created a fog. The solid formed precipitation and had a color change during the reaction proving it to be a chemical change. #3 There was green smoke and the crystals turned black. The green liquid turned dark green and continued to sizzle with

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together
