How will the concentration of h+ and oh− ions change when a substance with a ph 3.2 is added to water? both h+ and oh− will increase both h+ and oh− will decrease h+ will increase and oh− will decrease h+ will decrease and oh− will increase

the formula would be mgso4

mgso[subscript]4

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.
