0.29 M of the acid
Since the name of the acid (and the equation) is not given, you must assume that it is a 1:1 ratio. Use equation: volume of acid x molarity of acid = volume of base x...Read More

Volume of acid M of acid = V of base M of Base
M of acid = V of base M of Base/volume of acid
M of acid = 0.0155L0.215M/0.212 L
M of acid = 0.0157M

1 number change in pH indicates a factor of 10x change in strength.

The strength changes by a factor of 10. I.e. pH 2 is 10 times as strong as pH 3.

This is false, as if for example you have a basic solution and you use blue litmus paper, it will not change if it is basic. Therefore, it could be either alkaline or neutral
