Answer:
pH = 6.5
Explanation:
pH is the negative log of the hydronium concentration, [H⁺]. Since we are given the concentration, we can just plug it in the following equation:
pH = -log[H⁺] = -log[3.5 x 10^-7 M] = 6.5
Answer:
Yes, acetic acid could be used, but it would not be as effective as acetyl chloride or acetic anhydride. ... However, the acetic anhydride would still be reacting with an alcohol, so nothing changes in that respect. Also, the reaction would need to be done in basic solution.
count the elements in eqn MgI2 + Br2 -> MgBr2 + I2
1 Mg, 2I, 2Br on the left n
1 Mg, 2I, 2Br on the right
they are equal so the eqn is balanced
