Reactivity of Mg and Ca Essay Example for Free

Reactivity of Mg and Ca Essay Presentation The point of this reasonable is to watch the distinction in the reactivity among Mg and Ca when hot and cold water is included. Speculation We figure they will respond in a structure. Factors The autonomous variable was the temperature of the water and furthermore the amount of metal use in the examination and the reliant variable was the response. Hardware * Mg (s) * Ca (s) * Phenolphthalein * Beaker * Cold and high temp water * Sandpaper * Test tubes with rack System 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 Boiling 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 builds immediately. Before we dropped the phenolphthalein the arrangement was white, fig.3, however subsequent to including the phenolphthalein it turned pink, fig.4, which implies that the response is fundamental. The temperature remained the equivalent but since the water was hot the response was increasingly dangerous and speedier. 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? Truly on the grounds that calcium has more circles the particle has the less vitality it needs to part with electrons. For this situation the particle 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. What's more, the magnesium didnt respond much since it needs more vitality that the one that we gave it. Compose the decent 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 due to the pink color to the shading. We additionally discovered that calcium responded quicker than magnesium.
