Arrhenius Acid

Which characteristics describe an acid?

• sour, indicator turns red, pH less than 7, produces hydrogen ions (H⁺)
• bitter, slippery, indicator turns blue, pH greater than 7, produces hydroxide ions (OH^-)
• neutral, pH of 7
• sour, indicator turns red, pH greater than 7

Which characteristics describe a base?

• sour, indicator turns red, pH less than 7, produces hydrogen ions (H⁺)
