He volume required to reach the equivalence point of an acid-base titration depends on the volume and concentration of the acid or base to be titrated and on the concentration of the acid or base used to do the titration. it does not, however, depend on the whether or not the acid or base being titrated is strong or weak. explain.

the equivalence point occurs when the amount of added titrating substance is stoichiometrically equivalent to the present amount of the analyte or substance to be analyzed in the sample

Explanation:

in the equivalence point,  we have:

⇒ (Volume * Concentration )acid = (Volume * Concentration)base

As can be seen in the equation, at the point of quivalence there is complete salt formation, so the pH is calculated through the salt, therefore, it is not significant how strong or weak the base or acid is in the titration.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
