Explanation:
Hello!
In this case, since the energy involved during a heating process is shown below:
Whereas the specific heat of water is 4.184 J/(g°C), we can compute the heated mass of water by the addition of 11.9 kJ (11900 J) of heat as shown below:
Thus, by plugging in, we obtain:
Best regards!
Answer:- The hydroxide ion concentration of the solution is .
Solution:- The formula used to calculate pOH from hydroxide ion is:
When pOH is given and we are asked to calculate hydroxide ion concentration then we multiply both sides by negative sign and take antilog and what we get on doing this is:
pOH is given as 5.71 and we are asked to calculate hydrogen ion concentration. Let's plug in the given value in the formula:
= 0.00000195 or
So, the hydroxide ion concentration of the solution is .
