Reactivity of Mg and Ca Essay Example for Free

Reactivity of Mg and Ca Essay Presentation The point of this useful is to watch the distinction in the reactivity among Mg and Ca when hot and cold water is included. Theory We figure they will respond in a structure. Factors The free factor was the temperature of the water and furthermore the amount of metal use in the trial and the reliant variable was the response. Gear * Mg (s) * Ca (s) * Phenolphthalein * Beaker * Cold and heated water * Sandpaper * Test tubes with rack Strategy 1. The Magnesium was cleaned with sandpaper. 2. Two bits of magnesium was placed into two test cylinders and two bits of calcium was placed into two test tubes. 3. Cold water was included into two test tubes one with calcium one with magnesium. 4. Two beads of phenolphalein were included every one of the test tubes loaded up with cold water to watch the adjustment in ph. 5. Water was warmed over a Benson burner and filled the two test tubes without water while watching the responses. 6. Two beads of phenolphalein were included every one of the test tubes loaded up with cold water to watch the adjustment in ph. Perception Relative reactivity of Cold water High temp water Mg There was a base response. Fig. 1 There is a greater response than with the virus water. Fig. 2 Ca The temperature of the water expands immediately. Before we dropped the phenolphthalein the arrangement was white, fig.3, yet in the wake of including the phenolphthalein it turned pink, fig.4, which implies that the response is essential. The temperature remained the equivalent but since the water was hot the response was increasingly unstable and snappier. Before the phenolphthalein the arrangement was white, fig.3, and in the wake of dropping the phenolphthalein it turned pink, fig.4, which implies that is a fundamental arrangement. Results Are your outcomes as per what you have found out about reactivity? Indeed on the grounds that calcium has more circles the molecule has the less vitality it needs to part with electrons. For this situation the iota that has more circles is the calcium that is the reason it responds more than the magnesium since calcium needs less vitality to part with electrons. Furthermore, the magnesium didnt respond much since it needs more vitality that the one that we gave it. Compose the fair condition for the response among Mg and H2O: Mg (s) + H2O (l) MgO (s) + H2 (g) Vulnerabilities Other component may have been available. The high temp water may have been warmed more. End We discovered that both magnesium and calcium is essential arrangements as a result of the pink color to the shading. We likewise discovered that calcium responded quicker than magnesium.
