<span>Good Morning!
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.

Answer:
Explanation:
Hello,
In this case, since the reaction between HCl and NaOH is:
We notice a 1:1 molar ratio between the acid and the base, for that reason, in the equivalent point we find:
Thus, in terms of concentrations, we have:
Hence, we solve for the concentration of the acid to obtain:

When mixing these two systems, it should be noted that the temperature of these should go to equilibrium which would mean that heat absorbed should be equal to the heat rejected. We calculate as follows:
(mCΔT)1 = (mCΔT)2
(410)C(T - 25) = (100)C(95-T)
T = 38.73 °C
