Electrostatic induction in Solutions?

[Phyzwizz]

I was wondering if induction can apply to different chemical solutions. Take HCl for example. If a negatively charged rod were placed against the beaker in which HCl was held, would the H⁺ ions be pulled towards the rod. Would the same outcome appear in a neutral solution of NaCl (drawing the Na+ towards the negatively charged rod). Could a positively charged rod induce NaOH, drawing the OH^- ions towards it?

In general - no. There will be some very small increase in amount of ions on the phase boundary closest to the rod, measurable with a very precise electrochemistry techniques but nothing easy to observe using different methods..

Awesome, thanks.

So called double layer forms at the interface, effectively screening the field of the charged body so ions further in the solution will feel virtually no net force.

Yes, electrostatic induction can indeed apply to different chemical solutions. In the case of HCl, if a negatively charged rod is placed near the beaker, the H+ ions in the solution will be attracted to the rod due to their positive charge. Similarly, in a neutral solution of NaCl, the Na+ ions will be attracted to the negatively charged rod. This is because in both cases, the charged rod creates an electric field that causes the ions to move.

In the case of a positively charged rod inducing NaOH, the OH- ions will be attracted to the rod due to their negative charge. This phenomenon is known as electrostatic attraction, where opposite charges are attracted to each other.

It is important to note that the strength of the electrostatic force depends on the magnitude of the charges and the distance between them. So, the closer the charged rod is to the solution, the stronger the force and the greater the induced movement of ions.

In conclusion, electrostatic induction can indeed be observed in different chemical solutions, and the outcome will vary based on the type and concentration of ions present in the solution.
