Answer: Thus molarity of is 1.35 M
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Thus molarity of is 1.35 M
In a gas, the partcles are very far apart and loose.
Answer:
remains constant regardless of the pH
Explanation:
The pH refers to the hydrogen potential or hydrogen power that states the aqueous solution acidity. It varies from 0 to 14. The higher pH values denotes more basic solutions while on the other hand, the lower pH values denote more acidic
An acidic solution refers to a solution at which the hydrogen ions concentration is more than the hydroxide ions concentration
Therefore the ion product of water remains constant as the value of both hydrogen ions and hydroxide ions is relatively small as non-dissociated water concentration would remain the same.
Hence, the second option is correct
Answer:
40°C.
Explanation:
A calorie is defined as the amount of energy needed to raise the temperature of 1 gram of water through 1 °C. In the same way, a kcal would be defined as the amount of energy needed to raise the temperature of 1 kilogram of water through 1 °C.
Based on this definition, 100kcal will increase the emperature of the water in:
100kcal / 2,5kg = <em>40°C</em>
