What are the answers to studies weekly week 26 social studies? Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). A compound that can donate protons are considered acids but here in Methanol; as a result, water is a better proton donor, which makes Methanol a weak acid. Its acetate is used in the aniline acetate test for carbohydrates, identifying pentoses by conversion to furfural.
