    I need help with those please.









    Ok so the only thing I know is that HCL dissociates into ions in water. I have no clue what is the property of the solution or anything about methylbenzene..I tried searching everywhere I never found anything that I can understand.

    Thanks.

    I suspect what they are looking for in the first is an explanation of how and why halogens are reduced to halide ions and that they oxidise other things in the process. I would mention their position in the periodic table, high electron affinity, almost complete shells etc

    for the second, you are right that in water HCl dissociates (essentially completely) into ions. You need to explain why HCl ionises in water. This gives the resulting solution an important property (which you presumably know). It will also have electrical properties. Methylbenzene (old name toluene) is a non-polar organic solvent. So HCl dissolved in that won't ionise (why?) and the resulting solution will therefore not have the properties I mentioned earlier.

    So, you can fill in the blanks, right?
