The pH scale was given by Sorensen to quanitatively define strength of an acid and base
the pH scale extends from 0 to 14
For acids
The pH should be less than 7 [always]
For base
The pH should be more than 7 [always]
The pH seven is of neutral solution
pH = -log[H+]
Thus lower the pH higher the concentration of hydronium ion or protons produced by an acid
thus for the given pH scale interval [0-3] it represents strong acid [Which will give high concentration of protons on dissociation]
Answer:
Explanation
Density can be found by dividing the mass by the volume.
We know the iron sheet has a mass of 28.5 grams and the volume is 3.60 milliliters.
Substitute the values into the formula.
Divide.
Let's round to the nearest thousandth.
The 6 in the ten-thousandth tells us to round the 6 to a 7.
The density of iron is about <u>7.917 grams per milliliter.</u>
