Inessa05 [86]
<h3>Answer:</h3>

LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)

Salt formed is LiCl

<h3>Explanation:</h3>
  • Arrhenius acid refers to a substance that ionizes in water to generate protons or hydrogen ions.
  • Examples of Arrhenius acid include acids such as HCl, H₂SO₄ and HNO₃.
  • A reaction between Lithium hydroxide and an Arrhenius acid such as HCl will yield a salt and water.

That is;

LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)

  • The salt formed is LiCl
  • The reaction is an example of neutralization reaction.
