Describe the relationship between pH number and base strength

when the ph of s solution is less than 7,the solution is acidic.when the ph is more than 7,the solution is basic.The ph of solution depends on the strength of the acid or base in the solution. Measurements of the ph of dilute solutions are therefore good indicators of the relative strengths of acid and bases

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

the answer would be knowledge about cars!
