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 :) ### Making Solutions

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 ### What is the molarity of concentrated acid?

MOLARITY BY DILUTION Name Acids are usually acquired from chemical supply houses In concentrated form These acids are diluted to the desired concentration by adding water Since moles of acid before dilution = moles of acid after dilution and moles of acid = M x V then M1 x V~ = M2 x V2 Solve the following problems How much concentrated 18 M sulfuric acid is needed to 'prepare 250 ### Chapter 4 Solution Chemistry

concentrated solution are related to the final molarity (M 2) and volume (V 2) of a dilute solution by the equation: M 1 V 1 = M 2 V 2 Note that the units for volume and concentration don't actually matter in this equation sim to Figure 4 8 10 Examples: Molarity 1 What is the molarity of a solution made by ### BiochemPages

How is the Molarity of a percentage solution calculated? Using 70% concentrated Nitric Acid as an example: 70% Nitric Acid means that 100 grams of this acid contains 70 grams of HNO 3 The concentration is expressed at 70% wt /wt or 70 wt % HNO 3 Some chemists and analysts prefer to work in acid concentration units of Molarity (moles/liter) ### Molarity (M) Solution Concentration Stoichiometry

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 ### Concentrated acids and molarity?
