28 What makes a base a base? Mini Review: What makes an acid an acid?
What makes an acid strong? Which binary acids are strong? Which ternary acids are strong? What do acids taste like? What do acids react with? Describe an acid's pH. What happens to litmus in acid? Are acids electrolytes? What makes a base a base? What makes an base strong? Which bases are strong? What do bases taste like? What do bases react with? What do bases feel like? Describe a base's pH. What happens to litmus in base? Are bases electolytes?
