a)taste sour

b)feel slippery

c)crumble

d)corrode metal

The property is B) feeling slippery.

Explanation:

Based upon the pH as well as the types of ions released by a substance, it is called either as acid or base. Those substances whose pH is below 7 and releases hydrogen ions, they are called as acids. Those substances with pH above 7 and releases hydroxyl ion they are called as bases.

The following are the physical properties of the bases:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
