Molarity (M) Solution Concentration Stoichiometry

Molarity in Chemical Reactions In a chemical reaction • the volume and molarity (of a solution are used to determine the moles of a reactant or product volume (L) x molarity ( mol ) = moles 1 L • if molarity (mol/L) and moles are given the volume (L) can be determined mol x 1 L = volume (L) mol

concentrated acid?

28/04/2008Yes Acids have their own normal properties too (in terms of normality) However this may vary within acid to acid Even weak acids are good oxidizing agents like HF and CH3COOH Neutralization occurs between base and acid whether weak or strong concentrated or dilute About the occurrence of oxidation sorry there's none :)

3 3 Molarity – Chemistry

When performing calculations stepwise as in Example 4 it is important to refrain from rounding any intermediate calculation results which can lead to rounding errors in the final result In Example 4 the molar amount of NaCl computed in the first step 1 325 mol would be properly rounded to 1 32 mol if it were to be reported however although the last digit (5) is not significant it must

what is difference between dilute and concentrated acids

So concentrated acids are those in which have more amount of acid and less amount of water The number of H + ions in such solution is also high Conversely dilute acids are those in which amount of acid is less but water is more The number of H + ions in such solutions is low 18 View Full Answer CONCENTRATED ACIDS: Acids with high concentration of H3O+ ions DILUTED ACIDS: Acids with

pH pOH of strong acids and bases (video)

Even strong acids don't completely dissociate at high concentrations so a concentrated strong acid might be expected to have a higher pH than you would calculate On the other hand the hydrogen ion activity is higher for a concentrated strong acid than for a more dilute solution giving the pH a lower value than you would calculate Which has more of an effect the incomplete dissociation
