A25 ml solution of h2so4 is completely nuetralized by 18 ml of 1.0 ml of 1.0 m naoh using phenolphthalein as an indicator. what is the concentration of the h2so4 solution?

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
