hsengoren Posted April 3, 2003 Share Posted April 3, 2003 Please tell me. how come it is not "B" but "A" ? Can we count acids? Engraving is a process which the surface of metal is first covered with an acid and then inscribed with some sharp instrument. Quote Link to comment Share on other sites More sharing options...
Erin Posted April 19, 2003 Share Posted April 19, 2003 Grammar point in question: Can "acid" be a countable/count noun? This is a question that I wrote. I assume you've read my explanation here. Yes, "acid" can be count. Many scientific terms that we learn in ESL class are non-count are easily count nouns, especially on the TOEFL. Some examples: woods, salts, sugars, oils, metals, plastics, etc. The reason they can easily become count nouns is simply that since there are many varieties of these things, we can talk about them as count nouns. For example, there are many types of wood--cedar, mahogany, oak, sycamore, redwood, etc. There are many types of sugar--glucose, sucrose, lactose, and sucrose, for example. Get the idea?
