What else can I help you with?
Is dilute hcl strong acid or weak acid?
Its the other way around, hydrochloric acid is an example of a strong acid, whether dilute or otherwise. The strength of an acid is independent of its concentration.
Is dilute hydrocloric acid a strong acid?
Whether or not an acid is strong doesn't depend on concentration. Most definitions for acid strength depend on the acid dissociation constant (pKa). Strong acids are generally defined as those with a pKa less than -1.74. Since HCl meets this definition, it is a strong acid, regardless of concentration.
What specific property would litmus paper indicate?
It would indicate whether something is an acid or a base.
What was your strategy for testing whether a solution of strong acid and solution of weak acid can have the same pH?
I would first prepare solutions of both strong and weak acids at the same concentration. Then, I would measure the pH of each solution using a pH meter. If the pH values of the two solutions are the same, it would indicate that they have the same concentration of H+ ions despite their different strengths.
Can a strong electrolyte be a weak acid?
Strong acid is an expression in relation with the chemical properties of the acid and is used also in physical chemistry; dilute is a term only in relation with the concentration of the acid. Consequently strong acid and concentrated acid are not synonyms and a strong acid can be diluted.
What should be pH -value to be strong acid?
The pH will depend on the concentration of the acid, not on whether it is strong or weak.
What should be pH value to be strong acid?

Can you know from its name if an acid or base is strong or weak?
It's not possible to determine whether an acid or base is either strong or weak. The only way is to see it's concentration. To determine whether the liquid is an acid or base is easy. An acid's chemical formula always has Hydrogen ions. Example HNO3 or HCl. Bases always have OH or Hydroxide. Example NaOH2.
Why carbonic acid list in mineral acid if it is weak acid?
Someone should not have placed carbonic acid in the mineral acid list. For your edification though, whether or not an acid is strong or weak has no bearing on whether or not it is a mineral acid or an organic acid. Mineral acid is any acid comprised of one or more inorganic compounds and dissociate into a hydrogen ion and conjugate base.

Is sulphuric acid a strong acid or weak acid?
i thing strong acid
Is hydrochloric acid a strong acid?
Yes, hydrochloric acid is a strong acid.
