Answer:- Third option is correct, relative strength of orange juice to pure water is 1000 times
Solution:- pH is a way to represents the strength of the acids. Lower is the pH higher is the acid strength and higher is the pH lower is the acid strength. So, we could say that acid strength is inversely proportional to the pH.
From given pH value, we calculate the hydrogen ion concentration and then compare the hydrogen ion concentrations of the two acids to find out the relative strength.
for orange juice = and for pure water it is .
So, the relative acidity of orange juice compared to pure water =
= 1000
So, third option is correct, the relative strength of orange juice to pure water is 1000 times.
Count the atoms of each element in the reactants and the products. Use coefficients; place them in front of the compounds as needed.
On dissolving CO2 in plasma, some of it reacts with water to produce carbonic acid which gets dissociates to produce proton and bicarbonate ion with negative charge.
The pKa1 value indicates the acidic nature of carbonic acid and its value is 3.6. this value indicates the spontaneous nature of this reaction in alkaline solutions and helps in proceeding the reaction in forward direction. This results in dissolving of large amount of CO2 in plasma whereas Oxygen does not go any reaction f this type. Oxygen is a non polar molecule, so its solubility is quite lower in plasma.
Thus, CO2 is more soluble in plasma than O2
The answer will be:
Solubility of the mixture = 21.5/60 x 25 = 8.96
Hope this helps.
An element is a form of matter that is made of only one type of atom
