Answer:
![pH=-1.37](https://tex.z-dn.net/?f=%20pH%3D-1.37)
Explanation:
We are given that 25 mL of 0.10 M
is titrated with 0.10 M NaOH(aq).
We have to find the pH of solution
Volume of ![CH_3COOH=25mL=0.025 L](https://tex.z-dn.net/?f=CH_3COOH%3D25mL%3D0.025%20L)
Volume of NaoH=0.01 L
Volume of solution =25 +10=35 mL=![\frac{35}{1000}=0.035 L](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B1000%7D%3D0.035%20L)
Because 1 L=1000 mL
Molarity of NaOH=Concentration OH-=0.10M
Concentration of H+= Molarity of
=0.10 M
Number of moles of H+=Molarity multiply by volume of given acid
Number of moles of H+=
=0.0025 moles
Number of moles of
=0.001mole
Number of moles of H+ remaining after adding 10 mL base = 0.0025-0.001=0.0015 moles
Concentration of H+=![\frac{0.0015}{0.035}=4.28\times 10^{-2} m/L](https://tex.z-dn.net/?f=%5Cfrac%7B0.0015%7D%7B0.035%7D%3D4.28%5Ctimes%2010%5E%7B-2%7D%20m%2FL)
pH=-log [H+]=-log [4.28
]=-log4.28+2 log 10=-0.631+2
![pH=-1.37](https://tex.z-dn.net/?f=%20pH%3D-1.37)
Luster is the correct answer.
Answer:
Renewable energy
Explanation:
on the other hand, typically emits less CO2 than fossil fuels. In fact, renewables like solar and wind power—apart from construction and maintenance—don't emit any CO2 at all. With renewable energy, you can breathe easier, stay cooler, and create a more comfortable world for generations to come.
