You need to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. you have a 0.1292 m standard solution. you take a 25.00 ml sample of the original acid solution and dilute it to 250.0 ml. you then take a 10.00 ml sample of the dilute acid solution and titrate it with the standard solution. you need 14.24 ml of the standard solution to reach the endpoint. what is the concentration of the original acid solution?

OOF OOF OOF OOF OOF OOF OOF need points lol.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

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.
