Question

What do mean by precipitating reaction? Explain by giving examples.​

Answer 1

precipitate formation is given by the reactions in which an insoluble salt is formed like ok ba cl2 + H2 s o4 give b a s o4 + HCL in this reaction the b a s o4 formed is PPT this is insoluble in water and it's white in colour PPT has a great importance because they help us to distinguish various chemical and their reactions as the help in qualitative analysis of reactions colours to the solutions for crystals formed which are settled at the bottom of the beaker has PPT for precipitating reactions are very useful in qualitative analysis

Answer 2

$<v> A reaction in which an insoluble solid (called precipitate) is formed is called a precipitation reaction.For Example:</p><p>Na2CO3 (aq) + CaCl2 (aq) → CaCO3 (s) + 2NaCl (aq)</p><p>Sodium Carbonate + Calcium Chloride → Calcium Carbonate + Sodium Chloride</p><p>In this reaction, calcium carbonate is obtained as a precipitate. Hence, it is a precipitation reaction.$
