Which is NOT a property of a base??? 1). Turn red litmus blue. 2). Reacts with acids to produce a salt and water 3) Feel slippery 4) React with some metals to produce hydrogen gas

4

Explanation:

1: is true. That is exactly what happens. Red litmus goes from red to Blue (for base)

2: True. Bases react with acids to produce salts and water. For example

HCl (an acid) + Ba(OH)2 ( base) gives BaCl2 a salt + water

Balanced you get

2HCl + Ba(OH)2 ===> BaCl2 + 2HOH

3. You just have to know that this is true.

4. K + Mg(OH)2 ===> >

Not true

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

i don,t know so just answer mine
