Answer:
- <em>The function of an indicator in a titration is to </em><u>indicate the equivalence point.</u>
Explanation:
<em>Titration</em> is a procedure that uses the properties of the acid - base reactions to determine the mole concentration of an unknown solution from the known mole concentraion of other solution. One of the solution is the base and the other is the acid.
At the equivalence point, where the number of H⁺ ions is equal to the number of OH⁻ ions, there is a drastic change of the acidity (or alkalinity) of the solution.
Then, the chemical <em>indicators</em> are substances that change color at the equivalence point, telling the chemist that the equivalence point has been reached and the titration has finished.
Answer:
pH = 4.6
Explanation:
pH is the negative of the log of the hydrogen ion concentration
- log { 2.52 x 10^-5) = ~ 4.6
Answer: The above equation is balanced.
Explanation: Each individual atom are balanced. For Mg it has 1 atom in the reactant and product side. 2 atoms for H and 2 for Cl in both sides.
