For an acid and base reaction, select ALL statements that are TRUE. Supporting information: You can visit the link below to read more on this. https://openstax.org/books/chemistry-2e/pages/4-2-classifying-chemical-reactions e Base such as NaOH will have a pH BELOW 7. Acid and base reactions will always be endothermic. Acids such as HCI will have a pH ABOVE 7. OAcid and base reaction will produce water, salt and heat as the products. O Acid and base reaction is also known as neutralization reaction. CH3COOH is a weaker acid than HCI. HCI and H2S04 are considered as strong acids. 4 pts Question 2
