Which 0.1 m solution contains the highest concentration of oh- ions?

1. naoh
2. h2so4
3. kno3
4. nh4cl

explain why, : )

I think the correct answer would be NaOH since it is a strong base. As such, it would completely dissociates into its ions which are sodium and hydroxide ions. As compared to other options, this would be the best option. Hope this answers the question.

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.

Higher temperature = molecules move around faster. and vice versa.
