The concentration of hydroxide ion of a solution with a pH of 8. 25 is 1.77×
M
Calculation,
The pH of a solution tells us about concentration of the
ion ( proton ) in solution. However, if we know the value of pH , we can calculate pOH with the help of pH and from pOH we can find concentration of hydroxide ions in the solution.
pH + pOH = 14
8. 25 + pOH = 14
pOH = 14 - 8. 25 = 5.75
Since, pH = -㏒[
]
Similarly, pOH = -㏒[
]
If pOH = 5.75 , that means that -㏒[
] = 5.75 ,which means that,
[
] =
= 1.77×
.
So, we know that the concentration of the
ions in the solution with pH of 8.25 is 1.77×

Enthalpy is the change in energy. A cold pack will react endothermically and enthalpy will be positive and a heat pack will have negative enthalpy. You cannot determine which has more change in enthalpy unless you measure the temperature change. Eg. a heat pack went from 25c to 35c will have greater change in enthalpy then a cold pack going from 25 to 20c because the net temperature difference is greater
What is the element in which you are trying to find the number of molecules of?
Answer:
i believe the answer to your question is parallax or parsecs. im sorry im not very specific in this!
Explanation:
Answer:
1. Carbon dioxide, increase of green house gas
2. Stop deforestation, cut down amount of cars on the road (encourage public to take public transport), reduce the amount of time u on the air-conditioning
