NEED HELP ASAP PLEASE! You are given an unknown substance and asked to determine whether it is an acid or a base. It is a clear, colourless liquid. Give two different ways you could use to determine the type of substance. Be sure to indicate the result you would expect for each type of substance.

i have know clue i guess aluminum

i think lol

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
