Add Acid to Water or Water to Acid? Safely Diluting Acids
Diluting Sulfuric Acid. Sulfuric acid (H 2 SO 4) is the most dangerous common acid to dilute. Partly, this is because it reacts so violently with skin and clothing. Sulfuric acid quickly dehydrates proteins and carbohydrates in skin and muscle. The acid is much heavier than water, so water added to it reacts with the top layer first.
ELI5: What made Sulfuric Acid such a profound discovery for
Sulfuric acid is great in general, and is indeed a strong acid, but can be beaten in some places. Nitric acid will work on organic material and many metals more vigorously than sulfuric due to the produced conjugate base (NO3- nitrate) being a strong oxidizing agent, more so than sulfates in most aqueous environments.

Reaction of Copper and concentrated sulphuric acid
The copper takes the [O] and become CuO while sulfuric acid become sulfur dioxide. Then CuO reacts with remaining sulfuric acid to form $ce{Cu2SO4}$. This is a grossly simplified version of what probably happens, but it gives you a sense of why conc. $ce{H2SO4}$ can react with Cu. $endgroup$ –

What Are the Effects of Sulfuric Acid on Metal?
The effects of sulfuric acid on metal depend on a number of factors, including the type of metal, the concentration of the acid, and the temperature. Dilute sulfuric acid will, in theory, react with any metal that lies above hydrogen in the reactivity series by displacing hydrogen from the acid, releasing it as a gas and forming the sulfate salt of the metal.
Calculate the volume of acid needed to change the pH of an
At pH = 4, sulfuric acid will have lost 2 protons (you should have used 0.0001 for the $ce{H+}$ concentration rather than "x"). So you need half the amount of sulfuric acid compared to hydrochloric acid. In practical terms, you would hardly be able to add exactly 7.66 $mu$ L HCl to your solution. Typically, you would get a rough estimate of

Hence the green color of chlorine gas.
