His measurements are precise since his pH values are close to each other in a way that it was repeated in all measurements. On the contrary to accuracy, it is the closeness to the actual pH value he should have achieved. Therefore, Jose's results are precise but not accurate since his value is not close to the actual value of pH 4.

What happens when chlorine forms an ion?
zmey [24]

The chlorine usually forms a Chloride ion.

The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

What do you mean by Chlorine forming an ion?

Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.

The chloride ion is the anion  Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.

What will be the outcome of putting litmus paper into bleach?
yarga [219]
The correct answer is option C. The outcome of putting litmus paper into bleach would be that red paper turns blue, blue paper does not change. Domestic bleach is a strong base it typically has a pH of 11 to 13. So when testing for pH, it would really go with the basic characteristics.
