How conductive is brass?
Brass is conductive. It's an alloy of copper and zinc, both of which conduct electricity ( pure copper is better, though).
What is zinc sulphate on the pH scale?
The pH of zinc sulfate water solution is approx. 4,5.
How to test the presence of the reaction of zinc and hydrochloric acid?
Place a zinc strip in a clean test tube and add dilute hydrochloric acid. The strip dissolves and the result is a colorless solution. The products are zinc chloride and gaseous hydrogen.
What happens when a silver piece of zinc is placed in a blue solution of copper ii nitrate?
The silver piece of zinc dissolves forming zinc ions. Copper(ii) reduce into copper(i) ions. The blue color of the solution decreases.
When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
What is a substance that dissolves in solution to conduct an electrical current?
In a normal battery; Copper and Zinc.
Why does the blue colour of copper sulphate disappear when a zinc plate is dipped into it?
The copper plates out while the zinc dissolves, leaving a transparent zinc sulphate solution.

Is it a copper OR zinc penny that dissolves in phosphoric acid?
Zinc
What is zinc sulphate on the pH scale?
The pH of zinc sulfate water solution is approx. 4,5.
What is the pH of zinc oxide?
I measured a ZnO (Zinc Oxide) solution to be slightly basic with a pH of 7.69 in lab yesterday. Zinc Oxide is not something that dissolves in water, so it should not change the waters normal pH of 7. The solution I measured contained small suspended particles.

Why do the solution of the white precipitate of Zinc hydroxide dissolve in excess of Ammonium hydroxide?
Ammonium hydroxide dissolves anything that is less strong than itself. The white precipitate of zinc hydroxide is not the whole component. Therefore, it is not as strong.
When zinc rod is dipped in zinc sulphate sol then concentration of solution after time will be?
The concentration of the zinc sulphate solution will not change when a zinc rod is dipped into it. This is because zinc is already present in the solution as zinc ions, so the addition of a zinc rod will not alter the concentration of zinc ions in the solution.
Is Zinc electrically conductive?
Yes, like all metals.
Will zinc float on alcohol?
no because it dissolves together
