activity to show neutralisation reaction between acid and base
Answers
ANSWER
Material required
NaOH(1M) , HCl (1M) , Phenolphthalein , Burette, Pipette, Titration Flask.
Procedure
Acid + Base →Salt + Water
1) Take 5 mL of HCl in a conical flask .
2) Then add 5 mL of NaOH in the flask.
3) A neutralisation reaction will take place as NaCl will be formed.
Observation
The pink colour of phenolphthalein change to colourless
NaOH+HCl =========> NaCl +H2O
Phenolphthalein gives pink colour with NaOH( base ).When acid is added any react with acid to form NaCl and H2O .
when hole reaction of NaOH react with acid , it becomes colourless because it Rajesh injection is complete.
Conclusion
NaCl (base) react with HCL (acid) to form NaCl (acid) and H2O. It is example of Neutralization Reaction .
Neutralization reaction
Neutralization is a chemical reaction in which acid and base react to form salt and water. Hydrogen (H+) ions and hydroxide (OH- ions) reacts with each other to form water. The strong acid and strong base neutralization have the pH value of 7.
In chemistry, a reactivity series is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowes
