What would occur if #"sodium ethoxide"#, #H_3C-CH_2O^(-)""^(+)Na#, were added to water?

Answer 1

An acid-base reaction would occur....pdq...

You have sodium ethoxide, which the following equation says would react with water right away.

#H_3C-CH_2O^(-)Na^(+) + H_2O(l) rarr H_3C-CH_2OH + NaOH(aq)#

....are you sure they did not write #"sodium acetate"#, #H_3C-CO_2^(-)Na^+#, which has a definite (but high) water solubility?

On the other hand ethanol, #H_3C-CH_2OH# is INFINITELY MISCIBLE with water, in any and all proportion. #"1-propanol"#, option 3, has some limited water solubility, in that while it is capable of hydrogen bonding, the 3 carbon chain length limits its solubility in the polar water solvent.

Anyhow, please review the question.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
