Kingsley then adds 49.28 mL of NaOH to 250.00 mL of the HCOOH solution. The neutralization reaction resulted in 0.098 moles of HCOOH and 0.025 moles of HCOO left in solution. Determine the pH of the resulting solution. Which of the following acids would produce the highest pH at the equivalence point in a weak acid-strong base titration? Ka(HF) =6.8x10-4
Ka(HNO2) =4.5x10-4
Ka(HCIO2) =1.1x10-2
K(CH3COOH) =1.8x10-5
i. HCIO2
ii. CH3COOH
iii. HF
iv. HNO2

What volume of a 2.00 m stock solution of naoh is needed to prepare 150. ml of 0.40 m solution?

When the chemicals iron sulfide (fes) and hydrochloric acid (hcl) are combined, bubbles appear from the mixture. 1. does the appearance of bubbles indicate a physical or chemical change? 2. why do the bubbles indicate this change? 3. what property is this?
