Question

17. i) Explain why is hydrochloric acid a strong acid and acetic acid, a weak acid. How
can it be verified?
ii) Explain why aqueous solution of an acid conducts electricity
iii) You have four solutions A,B,C and D. The pH of solution A is 6, B is 9, Cis 12 and D
is 7,
a) Identify the most acidic and most basic solutions
b) Arrange the above four solutions in increasing order of Hiion concentration
c) State the change in colour of pH paper on dipping in solution C and D.
18. Dry pellets of base 'X' when kept​

Answer 1

17i- these are strong acids beacuse their ph value is less. it can be verified by using ph scale on that it show it's value through which we can easily identify whether the acid is strong Or weak.

ii- aqueous solution for acid conducts electricity beacuse it has ions in it and they are positvily Or negatively charged.

iii- A is most acidic and C is most basic
