WebChromium (III) hydroxide (Cr (OH) 3) is amphoteric, dissolving in acidic solutions to form [Cr (H 2 O) 6] 3+, and in basic solutions to form [Cr (OH) 6]3− . It is dehydrated by heating to form the green chromium (III) oxide (Cr 2 O 3 ), a stable oxide with a crystal structure identical to that of corundum. [18] Chromium (VI) [ edit]

Magnesium … WebIn a strong acid-strong base titration, the acid and base will react to form a neutral solution. At the equivalence point of the reaction, hydronium (H+) and hydroxide (OH-) ions will react to form water, leading to a pH of 7. This is true of all strong acid-strong base titrations. An example of this would be the titration of hydrochloric acid ...
