pH = - log[acid] = -log [H+]
pH= -log[10] = 1
Thus, pH is 1
if pH is 7, the solution is neutral and if pH is greater than 7 the solution is basic and if it is less than 7 the solution is acidic.
This solution have pH = 1, thus the solution is acidic.
Answer:
19,700 Joules
Explanation:
Quantity of heat (Q) = mc(T2-T1)
m (mass of ethanol) = 183g
c (specific heat capacity of ethanol) = 2.44J/g°C
T2 (boiling temperature of ethanol) = 78°C
T1 (initial temperature of ethanol) = 33.9°C
Q = 183×2.44(78 - 33.9) = 183×2.44×44.1 = 19691.532 = 19,700 Joules (to three significant digits)
M(NaOH)=15 g
v=600 ml=0.6 l
n(NaOH)=m(NaOH)/M(NaOH)
C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]
C=15g/[40g/mol*0.6 l]=0.625 mol/l
0.625M
[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875
