Sea water conducts electricity.
Which statements give the best explanation for this
a) Ions are able to move around in sea water
b) Electrons can pass from ion to ion in the sea water
c) The sea water contains more ions with positve charges than ions with negative charges
d) The sea water contains ions that have positive charges and ions that have negative charges
thanks
What do you think. Three answers are ridiculous.
Well i don't think its the first two but i'm not sure about the last two
I think it might be d
The best explanations for why sea water conducts electricity are statements (a), (b), and (d).
(a) Ions are able to move around in sea water: Sea water contains dissolved salts, such as sodium chloride (NaCl), which break down into positive sodium ions (Na+) and negative chloride ions (Cl-). These ions are free to move around in the water, creating a conductive medium.
(b) Electrons can pass from ion to ion in the sea water: When a potential difference is applied (such as through an electrical circuit), electrons can flow through the sea water, transferring from one ion to another. This movement of electrons enables the conduction of electricity.
(d) The sea water contains ions that have positive charges and ions that have negative charges: As mentioned, sea water contains both positive and negative ions. This means that there are particles with opposite charges present in the water, which is one of the key requirements for a substance to conduct electricity.
Conversely, statement (c) - "The sea water contains more ions with positive charges than ions with negative charges" - is not the best explanation. While it is true that sea water contains both positive and negative ions, the ratio of positive to negative ions may vary depending on the specific composition of the salts dissolved in the water. It is the presence and mobility of both positive and negative ions that allows sea water to conduct electricity, rather than a specific ratio between them.
