Single replacement or single displacement reactions
Explanation:
In a single replacement or displacement reaction, the activity series is useful in predicting whether the reaction will take place or not.
- In this reaction type, one substance is replacing another.
C + DE → CD + E
- The relative positions of the two elements in the activity series provides the driving force for the single replacement reaction.
- An element high up in the series will displace one that is lower in the series because it is more reactive.

Answer:
Explanation:
*Since the titration is between the strong acid HCl and the strong base Ca(OH)2, the pH at the equivalent point should be 7. On interpolation, we will obtain that 9.50mL and 9.82 mL of HCl is required to completely neutralized the given Ca(OH)2 solution.
*pH at the equivalence point =7
we know that pH + pOH = 14
Hence pOH= 14-7=7
pOH= -log(OH-)
The concentration of OH-= 10-pH= 1X10-7 M
One reason for the low solubility may be the higher reaction temperature, Another reason is the common ion effect.
D! It’s a pure substance and a compound
