How much value should be adjusted to use hydrochloric acid gas ph?

2.If D-tartaric acid (526-83-0) is used
How much value should be adjusted to use hydrochloric acid gas ph?

It's very urgent. Please help me answer it.

Wirh no values or metrics for your questions, they are vague and difficult to figure. How much? As much as it takes to reach your target ph
