Which of the following are properties of basic solutions?
a.They turn the dye litmus red.
b.They taste sour.
c.They feel slippery.
d.They react with active metals to produce hydrogen gas.
Both c and d are correct BUT if you are using a keyed on-line database, d may be counted wrong because most remember that as an acid reaction. Turns out that both acids and bases will produce hydrogen gas from active metals.
