Using titration, a student titrated a NaOH solution of unknown concentration with a standard solution of 0.10 M HCl. Using the data below from the burette, what is the concentration of the NaOH?
Burette readings:
Initial (HCl - 15.5 mL) (NaOH - 5.0 mL)
Final (HCl - 25.0 mL) (NaOH - 8.80 mL)
what is 0.25M

Explain what exothermic and endothermic mean in terms of energy and chemical reactions
Exothermic: heat is being released as a product
Endothermic: heat is being absorbed into the reaction
Define what a salt is and how it is made
Salts are an ionic compound made up of an anion and cation. Salts are formed by acid-base neutralization.
