As we all know that we should add acid to water not water to acid. Because it can give a lot heat out which can cause saviour burns to our skins and clothes. when the acid evolves a lot of heat it is a strong acid and when small amount of heat evolves it is a weak acid.
Acid and base when mixed in equal concentration neutralize each other.So if the water has both in equal concentration the water will not show the properties of the acid or the base.if any one i.e. acid or base is higher in concentration than the other the water will show its properties.

Metallic magnesium will cause rapid evolution of hydrogen gas when contacted with an acid in water solution, but will cause gas evolution much more slowly if at all when in contact with pure water.
All the carboxyllic acids are weak acids. You can show it by adding it to water and measuring its pH which would be higher as compared to pH of strong acids like HCl, H2SO4 .
diagonal relationships are shown by elements in periodic table with same charge to radius ratio, i.e. same polarizing power. important examples are beryllium and magnesium, boron and aluminium, carbon and silicon. diagonal relationship leads to "mimicking" of chemical properties, i.e. beryllium will show properties of magnesium anomalous to its group behavior, for instance formation of nitrites. similarly, boron will "mimic" aluminium and show properties like formation of amphoteric oxides. also boric acid is not a protic acid as it gives H+ only in water, just like aluminium.(B(OH)3+ H2O=>B(OH)4-)

The definition of an acid is the formation of the hydronium ion, H3O+. This comes about ONLY in the presence of water, H2O, where H2O + H+ ==> H3O+. It is a phenomenon of aqueous solutions, so water must be present.

water is a compound because it does not show its constituent's properties and has fixed proportion by mass,,,,,,,,,,,,,,,,

*when putting a piece of magnesium into dilute hydrocloric acid . *then hydrogen gas bubbles off. *this shows that magnesium react quickly in acid.

yes it is a role model show! is it not clear?
pH is a scale to show that the particular substance is acid or base. _0_____1___________________7_____8________________________12 Highly acidic Neutral Highly basic (water)
