Question

Can somebody help me with chemistry ?

Answer 1

Answer:

Sure!

A) Base

A) it will conduct electricity

Explanation:

To answer your question:

Phenolphthalein is one of the most widely used indicator in acid–base titrations. In titration setting, it turns colorless in acidic solutions and pink in basic solutions.

Thus the cleaning solution is A) Base

Another way to know it is a base is by looking at pH.

pH scale is 0-14 (0-6 Acidic, 7 Neutral, 8-14 basic) thus since cleaning solution has pH of 9.6 it falls under the pH range of 8-14 which is basic, hence your solution is basic.

HNO3 is a strong acid hence when put it in water it dissociates into ions. IONS are required to transmit electricity hence HNO3 will conduct electricity

Answer 2

Of course. What’s your question?
