The given question is incomplete. The complete question is:
An acidic solution at 25°C will have a hydronium ion concentration ________ and a pH value ________.
![[H_3O^+]](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D)
> 
M, pH < 7.00
< , pH < 7.00
< ,, pH > 7.00
> ,, pH > 7.00
Answer: > M, pH < 7.00
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
![7=-log[H_3O^+]](https://tex.z-dn.net/?f=7%3D-log%5BH_3O%5E%2B%5D)
![[H_3O^+]=10^{-7}](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D10%5E%7B-7%7D)
As pH of acids is less than 7, the hydronium ion concentration is greater than
Thus the correct option is > M, pH < 7.00
It is an approximation of its mass number. Each isotope of an element has a different mass number.
Answer:
The osmotic pressure is 10.8 atm
Explanation:
Formula for osmotic pressure is:
π = M . R . T
where M is molarity (mol/L)
R, Universal gas constant (0.082 l.atm/mol.K)
T, T° in K (T°C + 273)
π = M . 0.082 l.atm/mol.K . 318K
Let's calculate the molarity
In 800 mL ____ 60 g
1000 mL _____ 75 g
This is the mass in 1L of solution.
Molar mass glucose = 180.15 g/m
Mass / Molar mass = 75 g/ 180.15 g/m → moles
Moles = 0.416M
π = 0.416 mol/l . 0.082 l.atm/mol.K . 318K
π = 10.8 atm
Answer:
4 M
